### <a id="245"></a> ClickHouse release 24.5, 2024-05-30
|
||||
|
||||
#### Backward Incompatible Change
|
||||
* Renamed "inverted indexes" to "full-text indexes" which is a less technical / more user-friendly name. This also changes internal table metadata and breaks tables with existing (experimental) inverted indexes. Please make to drop such indexes before upgrade and re-create them after upgrade. [#62884](https://github.com/ClickHouse/ClickHouse/pull/62884) ([Robert Schulze](https://github.com/rschu1ze)).
|
||||
* Usage of functions `neighbor`, `runningAccumulate`, `runningDifferenceStartingWithFirstValue`, `runningDifference` deprecated (because it is error-prone). Proper window functions should be used instead. To enable them back, set `allow_deprecated_functions = 1` or set `compatibility = '24.4'` or lower. [#63132](https://github.com/ClickHouse/ClickHouse/pull/63132) ([Nikita Taranov](https://github.com/nickitat)).
|
||||
* Queries from `system.columns` will work faster if there is a large number of columns, but many databases or tables are not granted for `SHOW TABLES`. Note that in previous versions, if you grant `SHOW COLUMNS` to individual columns without granting `SHOW TABLES` to the corresponding tables, the `system.columns` table will show these columns, but in a new version, it will skip the table entirely. Remove trace log messages "Access granted" and "Access denied" that slowed down queries. [#63439](https://github.com/ClickHouse/ClickHouse/pull/63439) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Setting `replace_long_file_name_to_hash` is enabled by default for `MergeTree` tables. [#64457](https://github.com/ClickHouse/ClickHouse/pull/64457) ([Anton Popov](https://github.com/CurtizJ)). The data written with this setting can be read by server versions since 23.9. After you use ClickHouse with this setting enabled, you cannot downgrade to versions 23.8 and earlier.
|
||||
|
||||
#### New Feature
|
||||
* Adds the `Form` format to read/write a single record in the `application/x-www-form-urlencoded` format. [#60199](https://github.com/ClickHouse/ClickHouse/pull/60199) ([Shaun Struwig](https://github.com/Blargian)).
|
||||
* Added possibility to compress in CROSS JOIN. [#60459](https://github.com/ClickHouse/ClickHouse/pull/60459) ([p1rattttt](https://github.com/p1rattttt)).
|
||||
* Added possibility to do `CROSS JOIN` in temporary files if the size exceeds limits. [#63432](https://github.com/ClickHouse/ClickHouse/pull/63432) ([p1rattttt](https://github.com/p1rattttt)).
|
||||
* Support join with inequal conditions which involve columns from both left and right table. e.g. `t1.y < t2.y`. To enable, `SET allow_experimental_join_condition = 1`. [#60920](https://github.com/ClickHouse/ClickHouse/pull/60920) ([lgbo](https://github.com/lgbo-ustc)).
|
||||
* Maps can now have `Float32`, `Float64`, `Array(T)`, `Map(K, V)` and `Tuple(T1, T2, ...)` as keys. Closes [#54537](https://github.com/ClickHouse/ClickHouse/issues/54537). [#59318](https://github.com/ClickHouse/ClickHouse/pull/59318) ([李扬](https://github.com/taiyang-li)).
|
||||
* Introduce bulk loading to `EmbeddedRocksDB` by creating and ingesting SST file instead of relying on rocksdb build-in memtable. This help to increase importing speed, especially for long-running insert query to StorageEmbeddedRocksDB tables. Also, introduce `EmbeddedRocksDB` table settings. [#59163](https://github.com/ClickHouse/ClickHouse/pull/59163) [#63324](https://github.com/ClickHouse/ClickHouse/pull/63324) ([Duc Canh Le](https://github.com/canhld94)).
|
||||
* User can now parse CRLF with TSV format using a setting `input_format_tsv_crlf_end_of_line`. Closes [#56257](https://github.com/ClickHouse/ClickHouse/issues/56257). [#59747](https://github.com/ClickHouse/ClickHouse/pull/59747) ([Shaun Struwig](https://github.com/Blargian)).
|
||||
* A new setting `input_format_force_null_for_omitted_fields` that forces NULL values for omitted fields. [#60887](https://github.com/ClickHouse/ClickHouse/pull/60887) ([Constantine Peresypkin](https://github.com/pkit)).
|
||||
* Earlier our S3 storage and s3 table function didn't support selecting from archive container files, such as tarballs, zip, 7z. Now they allow to iterate over files inside archives in S3. [#62259](https://github.com/ClickHouse/ClickHouse/pull/62259) ([Daniil Ivanik](https://github.com/divanik)).
|
||||
* Support for conditional function `clamp`. [#62377](https://github.com/ClickHouse/ClickHouse/pull/62377) ([skyoct](https://github.com/skyoct)).
|
||||
* Add `NPy` output format. [#62430](https://github.com/ClickHouse/ClickHouse/pull/62430) ([豪肥肥](https://github.com/HowePa)).
|
||||
* `Raw` format as a synonym for `TSVRaw`. [#63394](https://github.com/ClickHouse/ClickHouse/pull/63394) ([Unalian](https://github.com/Unalian)).
|
||||
* Added a new SQL function `generateSnowflakeID` for generating Twitter-style Snowflake IDs. [#63577](https://github.com/ClickHouse/ClickHouse/pull/63577) ([Danila Puzov](https://github.com/kazalika)).
|
||||
* Added a new SQL function `generateUUIDv7` to generate version 7 UUIDs aka. timestamp-based UUIDs with random component. Also added a new function `UUIDToNum` to extract bytes from a UUID and a new function `UUIDv7ToDateTime` to extract timestamp component from a UUID version 7. [#62852](https://github.com/ClickHouse/ClickHouse/pull/62852) ([Alexey Petrunyaka](https://github.com/pet74alex)).
|
||||
* On Linux and MacOS, if the program has stdout redirected to a file with a compression extension, use the corresponding compression method instead of nothing (making it behave similarly to `INTO OUTFILE`). [#63662](https://github.com/ClickHouse/ClickHouse/pull/63662) ([v01dXYZ](https://github.com/v01dXYZ)).
|
||||
* Change warning on high number of attached tables to differentiate tables, views and dictionaries. [#64180](https://github.com/ClickHouse/ClickHouse/pull/64180) ([Francisco J. Jurado Moreno](https://github.com/Beetelbrox)).
|
||||
* Provide support for `azureBlobStorage` function in ClickHouse server to use Azure Workload identity to authenticate against Azure blob storage. If `use_workload_identity` parameter is set in config, [workload identity](https://github.com/Azure/azure-sdk-for-cpp/tree/main/sdk/identity/azure-identity#authenticate-azure-hosted-applications) is used for authentication. [#57881](https://github.com/ClickHouse/ClickHouse/pull/57881) ([Vinay Suryadevara](https://github.com/vinay92-ch)).
|
||||
* Add TTL information in the `system.parts_columns` table. [#63200](https://github.com/ClickHouse/ClickHouse/pull/63200) ([litlig](https://github.com/litlig)).
|
||||
|
||||
#### Experimental Features
|
||||
* Implement `Dynamic` data type that allows to store values of any type inside it without knowing all of them in advance. `Dynamic` type is available under a setting `allow_experimental_dynamic_type`. Reference: [#54864](https://github.com/ClickHouse/ClickHouse/issues/54864). [#63058](https://github.com/ClickHouse/ClickHouse/pull/63058) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* Allowed to create `MaterializedMySQL` database without connection to MySQL. [#63397](https://github.com/ClickHouse/ClickHouse/pull/63397) ([Kirill](https://github.com/kirillgarbar)).
|
||||
* Automatically mark a replica of Replicated database as lost and start recovery if some DDL task fails more than `max_retries_before_automatic_recovery` (100 by default) times in a row with the same error. Also, fixed a bug that could cause skipping DDL entries when an exception is thrown during an early stage of entry execution. [#63549](https://github.com/ClickHouse/ClickHouse/pull/63549) ([Alexander Tokmakov](https://github.com/tavplubix)).
|
||||
* Account failed files in `s3queue_tracked_file_ttl_sec` and `s3queue_traked_files_limit` for `StorageS3Queue`. [#63638](https://github.com/ClickHouse/ClickHouse/pull/63638) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
|
||||
#### Performance Improvement
|
||||
* A native parquet reader, which can read parquet binary to ClickHouse columns directly. Now this feature can be activated by setting `input_format_parquet_use_native_reader` to true. [#60361](https://github.com/ClickHouse/ClickHouse/pull/60361) ([ZhiHong Zhang](https://github.com/copperybean)).
|
||||
* Less contention in filesystem cache (part 4). Allow to keep filesystem cache not filled to the limit by doing additional eviction in the background (controlled by `keep_free_space_size(elements)_ratio`). This allows to release pressure from space reservation for queries (on `tryReserve` method). Also this is done in a lock free way as much as possible, e.g. should not block normal cache usage. [#61250](https://github.com/ClickHouse/ClickHouse/pull/61250) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Skip merging of newly created projection blocks during `INSERT`-s. [#59405](https://github.com/ClickHouse/ClickHouse/pull/59405) ([Nikita Taranov](https://github.com/nickitat)).
|
||||
* Process string functions `...UTF8` 'asciily' if input strings are all ascii chars. Inspired by https://github.com/apache/doris/pull/29799. Overall speed up by 1.07x~1.62x. Notice that peak memory usage had been decreased in some cases. [#61632](https://github.com/ClickHouse/ClickHouse/pull/61632) ([李扬](https://github.com/taiyang-li)).
|
||||
* Improved performance of selection (`{}`) globs in StorageS3. [#62120](https://github.com/ClickHouse/ClickHouse/pull/62120) ([Andrey Zvonov](https://github.com/zvonand)).
|
||||
* HostResolver has each IP address several times. If remote host has several IPs and by some reason (firewall rules for example) access on some IPs allowed and on others forbidden, than only first record of forbidden IPs marked as failed, and in each try these IPs have a chance to be chosen (and failed again). Even if fix this, every 120 seconds DNS cache dropped, and IPs can be chosen again. [#62652](https://github.com/ClickHouse/ClickHouse/pull/62652) ([Anton Ivashkin](https://github.com/ianton-ru)).
|
||||
* Function `splitByRegexp` is now faster when the regular expression argument is a single-character, trivial regular expression (in this case, it now falls back internally to `splitByChar`). [#62696](https://github.com/ClickHouse/ClickHouse/pull/62696) ([Robert Schulze](https://github.com/rschu1ze)).
|
||||
* Aggregation with 8-bit and 16-bit keys became faster: added min/max in FixedHashTable to limit the array index and reduce the `isZero()` calls during iteration. [#62746](https://github.com/ClickHouse/ClickHouse/pull/62746) ([Jiebin Sun](https://github.com/jiebinn)).
|
||||
* Add a new configuration`prefer_merge_sort_block_bytes` to control the memory usage and speed up sorting 2 times when merging when there are many columns. [#62904](https://github.com/ClickHouse/ClickHouse/pull/62904) ([LiuNeng](https://github.com/liuneng1994)).
|
||||
* `clickhouse-local` will start faster. In previous versions, it was not deleting temporary directories by mistake. Now it will. This closes [#62941](https://github.com/ClickHouse/ClickHouse/issues/62941). [#63074](https://github.com/ClickHouse/ClickHouse/pull/63074) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Micro-optimizations for the new analyzer. [#63429](https://github.com/ClickHouse/ClickHouse/pull/63429) ([Raúl Marín](https://github.com/Algunenano)).
|
||||
* Index analysis will work if `DateTime` is compared to `DateTime64`. This closes [#63441](https://github.com/ClickHouse/ClickHouse/issues/63441). [#63443](https://github.com/ClickHouse/ClickHouse/pull/63443) [#63532](https://github.com/ClickHouse/ClickHouse/pull/63532) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Speed up indices of type `set` a little (around 1.5 times) by removing garbage. [#64098](https://github.com/ClickHouse/ClickHouse/pull/64098) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Optimized vertical merges in tables with sparse columns. [#64311](https://github.com/ClickHouse/ClickHouse/pull/64311) ([Anton Popov](https://github.com/CurtizJ)).
|
||||
* Improve filtering of sparse columns: reduce redundant calls of `ColumnSparse::filter` to improve performance. [#64426](https://github.com/ClickHouse/ClickHouse/pull/64426) ([Jiebin Sun](https://github.com/jiebinn)).
|
||||
* Remove copying data when writing to the filesystem cache. [#63401](https://github.com/ClickHouse/ClickHouse/pull/63401) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Now backups with azure blob storage will use multicopy. [#64116](https://github.com/ClickHouse/ClickHouse/pull/64116) ([alesapin](https://github.com/alesapin)).
|
||||
* Allow to use native copy for azure even with different containers. [#64154](https://github.com/ClickHouse/ClickHouse/pull/64154) ([alesapin](https://github.com/alesapin)).
|
||||
* Finally enable native copy for azure. [#64182](https://github.com/ClickHouse/ClickHouse/pull/64182) ([alesapin](https://github.com/alesapin)).
|
||||
* Improve the iteration over sparse columns to reduce call of `size`. [#64497](https://github.com/ClickHouse/ClickHouse/pull/64497) ([Jiebin Sun](https://github.com/jiebinn)).
|
||||
|
||||
#### Improvement
|
||||
* Allow using `clickhouse-local` and its shortcuts `clickhouse` and `ch` with a query or queries file as a positional argument. Examples: `ch "SELECT 1"`, `ch --param_test Hello "SELECT {test:String}"`, `ch query.sql`. This closes [#62361](https://github.com/ClickHouse/ClickHouse/issues/62361). [#63081](https://github.com/ClickHouse/ClickHouse/pull/63081) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Enable plain_rewritable metadata for local and Azure (azure_blob_storage) object storages. [#63365](https://github.com/ClickHouse/ClickHouse/pull/63365) ([Julia Kartseva](https://github.com/jkartseva)).
|
||||
* Support English-style Unicode quotes, e.g. “Hello”, ‘world’. This is questionable in general but helpful when you type your query in a word processor, such as Google Docs. This closes [#58634](https://github.com/ClickHouse/ClickHouse/issues/58634). [#63381](https://github.com/ClickHouse/ClickHouse/pull/63381) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Allow trailing commas in the columns list in the INSERT query. For example, `INSERT INTO test (a, b, c, ) VALUES ...`. [#63803](https://github.com/ClickHouse/ClickHouse/pull/63803) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Better exception messages for the `Regexp` format. [#63804](https://github.com/ClickHouse/ClickHouse/pull/63804) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Allow trailing commas in the `Values` format. For example, this query is allowed: `INSERT INTO test (a, b, c) VALUES (4, 5, 6,);`. [#63810](https://github.com/ClickHouse/ClickHouse/pull/63810) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Make rabbitmq nack broken messages. Closes [#45350](https://github.com/ClickHouse/ClickHouse/issues/45350). [#60312](https://github.com/ClickHouse/ClickHouse/pull/60312) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* Fix a crash in asynchronous stack unwinding (such as when using the sampling query profiler) while interpreting debug info. This closes [#60460](https://github.com/ClickHouse/ClickHouse/issues/60460). [#60468](https://github.com/ClickHouse/ClickHouse/pull/60468) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Distinct messages for s3 error 'no key' for cases disk and storage. [#61108](https://github.com/ClickHouse/ClickHouse/pull/61108) ([Sema Checherinda](https://github.com/CheSema)).
|
||||
* The progress bar will work for trivial queries with LIMIT from `system.zeros`, `system.zeros_mt` (it already works for `system.numbers` and `system.numbers_mt`), and the `generateRandom` table function. As a bonus, if the total number of records is greater than the `max_rows_to_read` limit, it will throw an exception earlier. This closes [#58183](https://github.com/ClickHouse/ClickHouse/issues/58183). [#61823](https://github.com/ClickHouse/ClickHouse/pull/61823) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Support for "Merge Key" in YAML configurations (this is a weird feature of YAML, please never mind). [#62685](https://github.com/ClickHouse/ClickHouse/pull/62685) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Enhance error message when non-deterministic function is used with Replicated source. [#62896](https://github.com/ClickHouse/ClickHouse/pull/62896) ([Grégoire Pineau](https://github.com/lyrixx)).
|
||||
* Fix interserver secret for Distributed over Distributed from `remote`. [#63013](https://github.com/ClickHouse/ClickHouse/pull/63013) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Support `include_from` for YAML files. However, you should better use `config.d` [#63106](https://github.com/ClickHouse/ClickHouse/pull/63106) ([Eduard Karacharov](https://github.com/korowa)).
|
||||
* Keep previous data in terminal after picking from skim suggestions. [#63261](https://github.com/ClickHouse/ClickHouse/pull/63261) ([FlameFactory](https://github.com/FlameFactory)).
|
||||
* Width of fields (in Pretty formats or the `visibleWidth` function) now correctly ignores ANSI escape sequences. [#63270](https://github.com/ClickHouse/ClickHouse/pull/63270) ([Shaun Struwig](https://github.com/Blargian)).
|
||||
* Update the usage of error code `NUMBER_OF_ARGUMENTS_DOESNT_MATCH` by more accurate error codes when appropriate. [#63406](https://github.com/ClickHouse/ClickHouse/pull/63406) ([Yohann Jardin](https://github.com/yohannj)).
|
||||
* `os_user` and `client_hostname` are now correctly set up for queries for command line suggestions in clickhouse-client. This closes [#63430](https://github.com/ClickHouse/ClickHouse/issues/63430). [#63433](https://github.com/ClickHouse/ClickHouse/pull/63433) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Automatically correct `max_block_size` to the default value if it is zero. [#63587](https://github.com/ClickHouse/ClickHouse/pull/63587) ([Antonio Andelic](https://github.com/antonio2368)).
|
||||
* Add a build_id ALIAS column to trace_log to facilitate auto renaming upon detecting binary changes. This is to address [#52086](https://github.com/ClickHouse/ClickHouse/issues/52086). [#63656](https://github.com/ClickHouse/ClickHouse/pull/63656) ([Zimu Li](https://github.com/woodlzm)).
|
||||
* Enable truncate operation for object storage disks. [#63693](https://github.com/ClickHouse/ClickHouse/pull/63693) ([MikhailBurdukov](https://github.com/MikhailBurdukov)).
|
||||
* The loading of the keywords list is now dependent on the server revision and will be disabled for the old versions of ClickHouse server. CC @azat. [#63786](https://github.com/ClickHouse/ClickHouse/pull/63786) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
|
||||
* Clickhouse disks have to read server setting to obtain actual metadata format version. [#63831](https://github.com/ClickHouse/ClickHouse/pull/63831) ([Sema Checherinda](https://github.com/CheSema)).
|
||||
* Disable pretty format restrictions (`output_format_pretty_max_rows`/`output_format_pretty_max_value_width`) when stdout is not TTY. [#63942](https://github.com/ClickHouse/ClickHouse/pull/63942) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* Exception handling now works when ClickHouse is used inside AWS Lambda. Author: [Alexey Coolnev](https://github.com/acoolnev). [#64014](https://github.com/ClickHouse/ClickHouse/pull/64014) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Throw `CANNOT_DECOMPRESS` instread of `CORRUPTED_DATA` on invalid compressed data passed via HTTP. [#64036](https://github.com/ClickHouse/ClickHouse/pull/64036) ([vdimir](https://github.com/vdimir)).
|
||||
* A tip for a single large number in Pretty formats now works for Nullable and LowCardinality. This closes [#61993](https://github.com/ClickHouse/ClickHouse/issues/61993). [#64084](https://github.com/ClickHouse/ClickHouse/pull/64084) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Added knob `metadata_storage_type` to keep free space on metadata storage disk. [#64128](https://github.com/ClickHouse/ClickHouse/pull/64128) ([MikhailBurdukov](https://github.com/MikhailBurdukov)).
|
||||
* Add metrics, logs, and thread names around parts filtering with indices. [#64130](https://github.com/ClickHouse/ClickHouse/pull/64130) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
|
||||
* Metrics to track the number of directories created and removed by the `plain_rewritable` metadata storage, and the number of entries in the local-to-remote in-memory map. [#64175](https://github.com/ClickHouse/ClickHouse/pull/64175) ([Julia Kartseva](https://github.com/jkartseva)).
|
||||
* Ignore `allow_suspicious_primary_key` on `ATTACH` and verify on `ALTER`. [#64202](https://github.com/ClickHouse/ClickHouse/pull/64202) ([Azat Khuzhin](https://github.com/azat)).
|
||||
* The query cache now considers identical queries with different settings as different. This increases robustness in cases where different settings (e.g. `limit` or `additional_table_filters`) would affect the query result. [#64205](https://github.com/ClickHouse/ClickHouse/pull/64205) ([Robert Schulze](https://github.com/rschu1ze)).
|
||||
* Test that a non standard error code `QPSLimitExceeded` is supported and it is retryable error. [#64225](https://github.com/ClickHouse/ClickHouse/pull/64225) ([Sema Checherinda](https://github.com/CheSema)).

* Support `LEFT JOIN`, `ALL INNER JOIN`, and simple subqueries for parallel replicas (only with analyzer). New setting `parallel_replicas_prefer_local_join` chooses local `JOIN` execution (by default) vs `GLOBAL JOIN`. All tables should exist on every replica from `cluster_for_parallel_replicas`. New settings `min_external_table_block_size_rows` and `min_external_table_block_size_bytes` are used to squash small blocks that are sent for temporary tables (only with analyzer).

* Allow parallel and distributed processing for `S3Queue` table engine. For distributed processing use setting `s3queue_total_shards_num` (by default `1`). Setting `s3queue_processing_threads_num` previously was not allowed for Ordered processing mode, now it is allowed. Warning: settings `s3queue_processing_threads_num`(processing threads per each shard) and `s3queue_total_shards_num` for ordered mode change how metadata is stored (make the number of `max_processed_file` nodes equal to `s3queue_processing_threads_num * s3queue_total_shards_num`), so they must be the same for all shards and cannot be changed once at least one shard is created.

|
||||
* Hide sensitive info for s3queue [#60233](https://github.com/ClickHouse/ClickHouse/pull/60233) ([Kseniia Sumarokova](https://github.com/kssenii)).
|

Use such configuration with special care, because subqueries in TTL may lead to high memory consumption and, possibly, a non-deterministic result of TTL merge on different replicas (which is correctly handled by replication, however).

* This PR makes `RESTORE ON CLUSTER` wait for each `ReplicatedMergeTree` table to stop being readonly before attaching any restored parts to it. Earlier it didn't wait and it could try to attach some parts at nearly the same time as checking other replicas during the table's startup. In rare cases some parts could be not attached at all during `RESTORE ON CLUSTER` because of that issue.

ClickHouse utilizes third-party libraries for different purposes, e.g., to connect to other databases, to decode (encode) data during load (save) from (to) disk or to implement certain specialized SQL functions. To be independent of the available libraries in the target system, each third-party library is imported as a Git submodule into ClickHouse's source tree and compiled and linked with ClickHouse. A list of third-party libraries and their licenses can be obtained by the following query:

|
||||
## Adding and maintaining third-party libraries
|
||||
|
||||
1. Each third-party library must reside in a dedicated directory under the `contrib/` directory of the ClickHouse repository. Avoid dumps/copies of external code, instead use Git submodule feature to pull third-party code from an external upstream repository.
|
||||
2. Submodules are listed in `.gitmodule`. If the external library can be used as-is, you may reference the upstream repository directly. Otherwise, i.e. the external library requires patching/customization, create a fork of the official repository in the [ClickHouse organization in GitHub](https://github.com/ClickHouse).
|
||||
3. In the latter case, create a branch with `clickhouse/` prefix from the branch you want to integrate, e.g. `clickhouse/master` (for `master`) or `clickhouse/release/vX.Y.Z` (for a `release/vX.Y.Z` tag). The purpose of this branch is to isolate customization of the library from upstream work. For example, pulls from the upstream repository into the fork will leave all `clickhouse/` branches unaffected. Submodules in `contrib/` must only track `clickhouse/` branches of forked third-party repositories.
|
||||
4. To patch a fork of a third-party library, create a dedicated branch with `clickhouse/` prefix in the fork, e.g. `clickhouse/fix-some-desaster`. Finally, merge the patch branch into the custom tracking branch (e.g. `clickhouse/master` or `clickhouse/release/vX.Y.Z`) using a PR.
|
||||
5. Always create patches of third-party libraries with the official repository in mind. Once a PR of a patch branch to the `clickhouse/` branch in the fork repository is done and the submodule version in ClickHouse official repository is bumped, consider opening another PR from the patch branch to the upstream library repository. This ensures, that 1) the contribution has more than a single use case and importance, 2) others will also benefit from it, 3) the change will not remain a maintenance burden solely on ClickHouse developers.
|
||||
9. To update a submodule with changes in the upstream repository, first merge upstream `master` (or a new `versionX.Y.Z` tag) into the `clickhouse`-tracking branch in the fork repository. Conflicts with patches/customization will need to be resolved in this merge (see Step 4.). Once the merge is done, bump the submodule in ClickHouse to point to the new hash in the fork.
|
||||
Each third-party library must reside in a dedicated directory under the `contrib/` directory of the ClickHouse repository.
|
||||
Avoid dumping copies of external code into the library directory.
|
||||
Instead create a Git submodule to pull third-party code from an external upstream repository.
|
||||
|
||||
All submodules used by ClickHouse are listed in the `.gitmodule` file.
|
||||
If the library can be used as-is (the default case), you can reference the upstream repository directly.
|
||||
If the library needs patching, create a fork of the upstream repository in the [ClickHouse organization on GitHub](https://github.com/ClickHouse).
|
||||
|
||||
In the latter case, we aim to isolate custom patches as much as possible from upstream commits.
|
||||
To that end, create a branch with prefix `clickhouse/` from the branch or tag you want to integrate, e.g. `clickhouse/master` (for branch `master`) or `clickhouse/release/vX.Y.Z` (for tag `release/vX.Y.Z`).
|
||||
This ensures that pulls from the upstream repository into the fork will leave custom `clickhouse/` branches unaffected.
|
||||
Submodules in `contrib/` must only track `clickhouse/` branches of forked third-party repositories.
|
||||
|
||||
Patches are only applied against `clickhouse/` branches of external libraries.
|
||||
For that, push the patch as a branch with `clickhouse/`, e.g. `clickhouse/fix-some-desaster`.
|
||||
Then create a PR from the new branch against the custom tracking branch with `clickhouse/` prefix, (e.g. `clickhouse/master` or `clickhouse/release/vX.Y.Z`) and merge the patch.
|
||||
|
||||
Create patches of third-party libraries with the official repository in mind and consider contributing the patch back to the upstream repository.
|
||||
This makes sure that others will also benefit from the patch and it will not be a maintenance burden for the ClickHouse team.
|
||||
|
||||
To pull upstream changes into the submodule, you can use two methods:
|
||||
- (less work but less clean): merge upstream `master` into the corresponding `clickhouse/` tracking branch in the forked repository. You will need to resolve merge conflicts with previous custom patches. This method can be used when the `clickhouse/` branch tracks an upstream development branch like `master`, `main`, `dev`, etc.
|
||||
- (more work but cleaner): create a new branch with `clickhouse/` prefix from the upstream commit or tag you like to integrate. Then re-apply all existing patches using new PRs (or squash them into a single PR). This method can be used when the `clickhouse/` branch tracks a specific upstream version branch or tag. It is cleaner in the sense that custom patches and upstream changes are better isolated from each other.
|
||||
|
||||
Once the submodule has been updated, bump the submodule in ClickHouse to point to the new hash in the fork.

## generateUUIDv7ThreadMonotonic
|
||||
|
||||
Generates a [UUID](../data-types/uuid.md) of [version 7](https://datatracker.ietf.org/doc/html/draft-peabody-dispatch-new-uuid-format-04).
|
||||
|
||||
The generated UUID contains the current Unix timestamp in milliseconds (48 bits), followed by version "7" (4 bits), a counter (42 bit) to distinguish UUIDs within a millisecond (including a variant field "2", 2 bit), and a random field (32 bits).
|
||||
For any given timestamp (unix_ts_ms), the counter starts at a random value and is incremented by 1 for each new UUID until the timestamp changes.
|
||||
In case the counter overflows, the timestamp field is incremented by 1 and the counter is reset to a random new start value.
|
||||
|
||||
This function behaves like [generateUUIDv7](#generateUUIDv7) but gives no guarantee on counter monotony across different simultaneous requests.
|
||||
Monotonicity within one timestamp is guaranteed only within the same thread calling this function to generate UUIDs.

generateUUIDv7ThreadMonotonic([expr])
|
||||
```
|
||||
|
||||
**Arguments**
|
||||
|
||||
- `expr` — An arbitrary [expression](../syntax.md#syntax-expressions) used to bypass [common subexpression elimination](../functions/index.md#common-subexpression-elimination) if the function is called multiple times in a query. The value of the expression has no effect on the returned UUID. Optional.
|
||||
|
||||
**Returned value**
|
||||
|
||||
A value of type UUIDv7.
|
||||
|
||||
**Usage example**
|
||||
|
||||
First, create a table with a column of type UUID, then insert a generated UUIDv7 into the table.
|
||||
|
||||
``` sql
|
||||
CREATE TABLE tab (uuid UUID) ENGINE = Memory;
|
||||
|
||||
INSERT INTO tab SELECT generateUUIDv7ThreadMonotonic();
|
||||
|
||||
SELECT * FROM tab;
|
||||
```
|
||||
|
||||
Result:
|
||||
|
||||
```response

## generateUUIDv7NonMonotonic
|

Generates a [UUID](../data-types/uuid.md) of [version 7](https://datatracker.ietf.org/doc/html/draft-peabody-dispatch-new-uuid-format-04).
|
||||
|
||||
The generated UUID contains the current Unix timestamp in milliseconds (48 bits), followed by version "7" (4 bits) and a random field (76 bits, including a 2-bit variant field "2").
|
||||
|
||||
This function is the fastest `generateUUIDv7*` function but it gives no monotonicity guarantees within a timestamp.

Генерирует идентификатор [UUID версии 7](https://datatracker.ietf.org/doc/html/draft-peabody-dispatch-new-uuid-format-04). Генерируемый UUID состоит из 48-битной временной метки (Unix time в миллисекундах), маркеров версии 7 и варианта 2, монотонно возрастающего счётчика для данной временной метки и случайных данных в указанной ниже последовательности. Для каждой новой временной метки счётчик стартует с нового случайного значения, а для следующих UUIDv7 он увеличивается на единицу. В случае переполнения счётчика временная метка принудительно увеличивается на 1, и счётчик снова стартует со случайного значения. Данная функция является ускоренным аналогом функции `generateUUIDv7` за счёт потери гарантии монотонности счётчика при одной и той же метке времени между одновременно исполняемыми разными запросами. Монотонность счётчика гарантируется только в пределах одного треда, исполняющего данную функцию для генерации нескольких UUID.

``` sql
|
||||
generateUUIDv7ThreadMonotonic([x])
|
||||
```
|
||||
|
||||
**Аргументы**
|
||||
|
||||
- `x` — [выражение](../syntax.md#syntax-expressions), возвращающее значение одного из [поддерживаемых типов данных](../data-types/index.md#data_types). Значение используется, чтобы избежать [склейки одинаковых выражений](index.md#common-subexpression-elimination), если функция вызывается несколько раз в одном запросе. Необязательный параметр.
|
||||
|
||||
**Возвращаемое значение**
|
||||
|
||||
Значение типа [UUID](../../sql-reference/functions/uuid-functions.md).
|
||||
|
||||
**Пример использования**

На апрель 2024 года UUIDv7 находится в статусе черновика и его раскладка по битам может в итоге измениться.
|
||||
::::
|
||||
|
||||
**Синтаксис**
|
||||
|
||||
``` sql
|
||||
generateUUIDv7NonMonotonic([x])
|
||||
```
|
||||
|
||||
**Аргументы**
|
||||
|
||||
- `x` — [выражение](../syntax.md#syntax-expressions), возвращающее значение одного из [поддерживаемых типов данных](../data-types/index.md#data_types). Значение используется, чтобы избежать [склейки одинаковых выражений](index.md#common-subexpression-elimination), если функция вызывается несколько раз в одном запросе. Необязательный параметр.
|
||||
|
||||
**Возвращаемое значение**
|
||||
|
||||
Значение типа [UUID](../../sql-reference/functions/uuid-functions.md).
|
||||
|
||||
**Пример использования**
|
||||
|
||||
Этот пример демонстрирует, как создать таблицу с UUID-колонкой и добавить в нее сгенерированный UUIDv7.
|
||||
|
||||
``` sql
|
||||
CREATE TABLE t_uuid (x UUID) ENGINE=TinyLog
|
||||
|
||||
INSERT INTO t_uuid SELECT generateUUIDv7NonMonotonic()
|
||||
|
||||
SELECT * FROM t_uuid
|
||||
```
|
||||
|
||||
``` text
|
||||
┌────────────────────────────────────x─┐
|
||||
│ 018f05af-f4a8-778f-beee-1bedbc95c93b │
|
||||
└──────────────────────────────────────┘
|
||||
```
|
||||
|
||||
**Пример использования, для генерации нескольких значений в одной строке**
|
||||
|
||||
```sql
|
||||
SELECT generateUUIDv7NonMonotonic(1), generateUUIDv7NonMonotonic(7)
|
||||
┌─generateUUIDv7NonMonotonic(1)────────┬─generateUUIDv7NonMonotonic(2)────────┐
|
||||
│ 018f05b1-8c2e-7567-a988-48d09606ae8c │ 018f05b1-8c2e-7946-895b-fcd7635da9a0 │
|
||||
└──────────────────────────────────────┴──────────────────────────────────────┘
|
||||
```
|
||||
|
||||
## empty {#empty}
|
||||
|
||||
Проверяет, является ли входной UUID пустым.

/** Projection names is name of query tree node that is used in projection part of query node.
|
||||
* Example: SELECT id FROM test_table;
|
||||
* `id` is projection name of column node
|
||||
*
|
||||
* Example: SELECT id AS id_alias FROM test_table;
|
||||
* `id_alias` is projection name of column node
|
||||
*
|
||||
* Calculation of projection names is done during expression nodes resolution. This is done this way
|
||||
* because after identifier node is resolved we lose information about identifier name. We could
|
||||
* potentially save this information in query tree node itself, but that would require to clone it in some cases.
|
||||
* Example: SELECT big_scalar_subquery AS a, a AS b, b AS c;
|
||||
* All 3 nodes in projection are the same big_scalar_subquery, but they have different projection names.
|
||||
* If we want to save it in query tree node, we have to clone subquery node that could lead to performance degradation.
|
||||
*
|
||||
* Possible solution is to separate query node metadata and query node content. So only node metadata could be cloned
|
||||
* if we want to change projection name. This solution does not seem to be easy for client of query tree because projection
|
||||
* name will be part of interface. If we potentially could hide projection names calculation in analyzer without introducing additional
|
||||
* changes in query tree structure that would be preferable.
|
||||
*
|
||||
* Currently each resolve method returns projection names array. Resolve method must compute projection names of node.
|
||||
* If node is resolved as list node this is case for `untuple` function or `matcher` result projection names array must contain projection names
|
||||
* for result nodes.
|
||||
* If node is not resolved as list node, projection names array contain single projection name for node.
|
||||
*
|
||||
* Rules for projection names:
|
||||
* 1. If node has alias. It is node projection name.
|
||||
* Except scenario where `untuple` function has alias. Example: SELECT untuple(expr) AS alias, alias.
|
||||
*
|
||||
* 2. For constant it is constant value string representation.
|
||||
*
|
||||
* 3. For identifier:
|
||||
* If identifier is resolved from JOIN TREE, we want to remove additional identifier qualifications.
|
||||
* Example: SELECT default.test_table.id FROM test_table.
|
||||
* Result projection name is `id`.
|
||||
*
|
||||
* Example: SELECT t1.id FROM test_table_1 AS t1, test_table_2 AS t2
|
||||
* In example both test_table_1, test_table_2 have `id` column.
|
||||
* In such case projection name is `t1.id` because if additional qualification is removed then column projection name `id` will be ambiguous.
|
||||
*
|
||||
* Example: SELECT default.test_table_1.id FROM test_table_1 AS t1, test_table_2 AS t2
|
||||
* In such case projection name is `test_table_1.id` because we remove unnecessary database qualification, but table name qualification cannot be removed
|
||||
* because otherwise column projection name `id` will be ambiguous.
|
||||
*
|
||||
* If identifier is not resolved from JOIN TREE. Identifier name is projection name.
|
||||
* Except scenario where `untuple` function resolved using identifier. Example: SELECT untuple(expr) AS alias, alias.
|
||||
* Example: SELECT sum(1, 1) AS value, value.
|
||||
* In such case both nodes have `value` projection names.
|
||||
*
|
||||
* Example: SELECT id AS value, value FROM test_table.
|
||||
* In such case both nodes have have `value` projection names.
|
||||
*
|
||||
* Special case is `untuple` function. If `untuple` function specified with alias, then result nodes will have alias.tuple_column_name projection names.
|
||||
* Example: SELECT cast(tuple(1), 'Tuple(id UInt64)') AS value, untuple(value) AS a;
|
||||
* Result projection names are `value`, `a.id`.
|
||||
*

* If `untuple` function does not have alias then result nodes will have `tupleElement(untuple_expression_projection_name, 'tuple_column_name') projection names.
|
||||
*
|
||||
* Example: SELECT cast(tuple(1), 'Tuple(id UInt64)') AS value, untuple(value);
|
||||
* Result projection names are `value`, `tupleElement(value, 'id')`;
|
||||
*
|
||||
* 4. For function:
|
||||
* Projection name consists from function_name(parameters_projection_names)(arguments_projection_names).
|
||||
* Additionally if function is window function. Window node projection name is used with OVER clause.
|
||||
* Example: function_name (parameters_names)(argument_projection_names) OVER window_name;
|
||||
* Example: function_name (parameters_names)(argument_projection_names) OVER (PARTITION BY id ORDER BY id).
|
||||
* Example: function_name (parameters_names)(argument_projection_names) OVER (window_name ORDER BY id).
|
||||
*
|
||||
* 5. For lambda:
|
||||
* If it is standalone lambda that returns single expression, function projection name is used.
|
||||
* Example: WITH (x -> x + 1) AS lambda SELECT lambda(1).
|
||||
* Projection name is `lambda(1)`.
|
||||
*
|
||||
* If is it standalone lambda that returns list, projection names of list nodes are used.
|
||||
* Example: WITH (x -> *) AS lambda SELECT lambda(1) FROM test_table;
|
||||
* If test_table has two columns `id`, `value`. Then result projection names are `id`, `value`.
|
||||
*
|
||||
* If lambda is argument of function.
|
||||
* Then projection name consists from lambda(tuple(lambda_arguments)(lambda_body_projection_name));
|
||||
*
|
||||
* 6. For matcher:
|
||||
* Matched nodes projection names are used as matcher projection names.
|
||||
*
|
||||
* Matched nodes must be qualified if needed.
|
||||
* Example: SELECT * FROM test_table_1 AS t1, test_table_2 AS t2.
|
||||
* In example table test_table_1 and test_table_2 both have `id`, `value` columns.
|
||||
* Matched nodes after unqualified matcher resolve must be qualified to avoid ambiguous projection names.
|
||||
* Result projection names must be `t1.id`, `t1.value`, `t2.id`, `t2.value`.
|
||||
*
|
||||
* There are special cases
|
||||
* 1. For lambda inside APPLY matcher transformer:
|
||||
* Example: SELECT * APPLY x -> toString(x) FROM test_table.
|
||||
* In such case lambda argument projection name `x` will be replaced by matched node projection name.
|
||||
* If table has two columns `id` and `value`. Then result projection names are `toString(id)`, `toString(value)`;
|
||||
*
|
||||
* 2. For unqualified matcher when JOIN tree contains JOIN with USING.
|
||||
* Example: SELECT * FROM test_table_1 AS t1 INNER JOIN test_table_2 AS t2 USING(id);
|
||||
* Result projection names must be `id`, `t1.value`, `t2.value`.
|
||||
*
|
||||
* 7. For subquery:
|
||||
* For subquery projection name consists of `_subquery_` prefix and implementation specific unique number suffix.
|
||||
* Example: SELECT (SELECT 1), (SELECT 1 UNION DISTINCT SELECT 1);
|
||||
* Result projection name can be `_subquery_1`, `subquery_2`;
|
||||
*
|
||||
* 8. For table:
|
||||
* Table node can be used in expression context only as right argument of IN function. In that case identifier is used
|
||||
* as table node projection name.
|
||||
* Example: SELECT id IN test_table FROM test_table;
|
||||
* Result projection name is `in(id, test_table)`.

/** Query analyzer implementation overview. Please check documentation in QueryAnalysisPass.h first.
|
||||
* And additional documentation for each method, where special cases are described in detail.
|
||||
*
|
||||
* Each node in query must be resolved. For each query tree node resolved state is specific.
|
||||
*
|
||||
* For constant node no resolve process exists, it is resolved during construction.
|
||||
*
|
||||
* For table node no resolve process exists, it is resolved during construction.
|
||||
*
|
||||
* For function node to be resolved parameters and arguments must be resolved, function node must be initialized with concrete aggregate or
|
||||
* non aggregate function and with result type.
|
||||
*
|
||||
* For lambda node there can be 2 different cases.
|
||||
* 1. Standalone: WITH (x -> x + 1) AS lambda SELECT lambda(1); Such lambdas are inlined in query tree during query analysis pass.
|
||||
* 2. Function arguments: WITH (x -> x + 1) AS lambda SELECT arrayMap(lambda, [1, 2, 3]); For such lambda resolution must
|
||||
* set concrete lambda arguments (initially they are identifier nodes) and resolve lambda expression body.
|
||||
*
|
||||
* For query node resolve process must resolve all its inner nodes.
|
||||
*
|
||||
* For matcher node resolve process must replace it with matched nodes.
|
||||
*
|
||||
* For identifier node resolve process must replace it with concrete non identifier node. This part is most complex because
|
||||
* for identifier resolution scopes and identifier lookup context play important part.
|
||||
*
|
||||
* ClickHouse SQL support lexical scoping for identifier resolution. Scope can be defined by query node or by expression node.
|
||||
* Expression nodes that can define scope are lambdas and table ALIAS columns.
|
||||
*
|
||||
* Identifier lookup context can be expression, function, table.
|
||||
*
|
||||
* Examples: WITH (x -> x + 1) as func SELECT func() FROM func; During function `func` resolution identifier lookup is performed
|
||||
* in function context.
|
||||
*
|
||||
* If there are no information of identifier context rules are following:
|
||||
* 1. Try to resolve identifier in expression context.
|
||||
* 2. Try to resolve identifier in function context, if it is allowed. Example: SELECT func(arguments); Here func identifier cannot be resolved in function context
|
||||
* because query projection does not support that.
|
||||
* 3. Try to resolve identifier in table context, if it is allowed. Example: SELECT table; Here table identifier cannot be resolved in function context
|
||||
* because query projection does not support that.
|
||||
*
|
||||
* TODO: This does not supported properly before, because matchers could not be resolved from aliases.
|
||||
*
|
||||
* Identifiers are resolved with following rules:
|
||||
* Resolution starts with current scope.
|
||||
* 1. Try to resolve identifier from expression scope arguments. Lambda expression arguments are greatest priority.
|
||||
* 2. Try to resolve identifier from aliases.
|
||||
* 3. Try to resolve identifier from join tree if scope is query, or if there are registered table columns in scope.
|
||||
* Steps 2 and 3 can be changed using prefer_column_name_to_alias setting.
|
||||
* 4. If it is table lookup, try to resolve identifier from CTE.
|
||||
* If identifier could not be resolved in current scope, resolution must be continued in parent scopes.
|
||||
* 5. Try to resolve identifier from parent scopes.
|
||||
*
|
||||
* Additional rules about aliases and scopes.
|
||||
* 1. Parent scope cannot refer alias from child scope.
|
||||
* 2. Child scope can refer to alias in parent scope.
|
||||
*
|
||||
* Example: SELECT arrayMap(x -> x + 1 AS a, [1,2,3]), a; Identifier a is unknown in parent scope.
|
||||
* Example: SELECT a FROM (SELECT 1 as a); Here we do not refer to alias a from child query scope. But we query it projection result, similar to tables.
|
||||
* Example: WITH 1 as a SELECT (SELECT a) as b; Here in child scope identifier a is resolved using alias from parent scope.
|
||||
*
|
||||
* Additional rules about identifier binding.
|
||||
* Bind for identifier to entity means that identifier first part match some node during analysis.
|
||||
* If other parts of identifier cannot be resolved in that node, exception must be thrown.
|
||||
*
|
||||
* Example:
|
||||
* CREATE TABLE test_table (id UInt64, compound_value Tuple(value UInt64)) ENGINE=TinyLog;
|
||||
* SELECT compound_value.value, 1 AS compound_value FROM test_table;
|
||||
* Identifier first part compound_value bound to entity with alias compound_value, but nested identifier part cannot be resolved from entity,
|
||||
* lookup should not be continued, and exception must be thrown because if lookup continues that way identifier can be resolved from join tree.
|
||||
*
|
||||
* TODO: This was not supported properly before analyzer because nested identifier could not be resolved from alias.
|
||||
*
|
||||
* More complex example:
|
||||
* CREATE TABLE test_table (id UInt64, value UInt64) ENGINE=TinyLog;
|
||||
* WITH cast(('Value'), 'Tuple (value UInt64') AS value SELECT (SELECT value FROM test_table);
|
||||
* Identifier first part value bound to test_table column value, but nested identifier part cannot be resolved from it,
|
||||
* lookup should not be continued, and exception must be thrown because if lookup continues identifier can be resolved from parent scope.
|
||||
*
|
||||
* TODO: Update exception messages
|
||||
* TODO: Table identifiers with optional UUID.
|
||||
* TODO: Lookup functions arrayReduce(sum, [1, 2, 3]);
|
||||
* TODO: Support function identifier resolve from parent query scope, if lambda in parent scope does not capture any columns.

/** Visitor that extracts expression and function aliases from node and initialize scope tables with it.
|

* Does not go into child lambdas and queries.
|
||||
*
|
||||
* Important:
|
||||
* Identifier nodes with aliases are added both in alias to expression and alias to function map.
|
||||
*
|
||||
* These is necessary because identifier with alias can give alias name to any query tree node.
|
||||
*
|
||||
* Example:
|
||||
* WITH (x -> x + 1) AS id, id AS value SELECT value(1);
|
||||
* In this example id as value is identifier node that has alias, during scope initialization we cannot derive
|
||||
* that id is actually lambda or expression.
|
||||
*
|
||||
* There are no easy solution here, without trying to make full featured expression resolution at this stage.
|
||||
* Example:
|
||||
* WITH (x -> x + 1) AS id, id AS id_1, id_1 AS id_2 SELECT id_2(1);
|
||||
* Example: SELECT a, b AS a, b AS c, 1 AS c;
|
||||
*
|
||||
* It is client responsibility after resolving identifier node with alias, make following actions:
|
||||
* 1. If identifier node was resolved in function scope, remove alias from scope expression map.
|
||||
* 2. If identifier node was resolved in expression scope, remove alias from scope function map.
|
||||
*
|
||||
* That way we separate alias map initialization and expressions resolution.
