* Do not allow const and non-deterministic secondary indices [#46839](https://github.com/ClickHouse/ClickHouse/pull/46839) ([Anton Popov](https://github.com/CurtizJ)).
#### New Feature
* Add new mode for splitting the work on replicas using settings `parallel_replicas_custom_key` and `parallel_replicas_custom_key_filter_type`. If the cluster consists of a single shard with multiple replicas, up to `max_parallel_replicas` will be randomly picked and turned into shards. For each shard, a corresponding filter is added to the query on the initiator before being sent to the shard. If the cluster consists of multiple shards, it will behave the same as `sample_key` but with the possibility to define an arbitrary key. [#45108](https://github.com/ClickHouse/ClickHouse/pull/45108) ([Antonio Andelic](https://github.com/antonio2368)).

[#45108](https://github.com/ClickHouse/ClickHouse/pull/45108) ([Antonio Andelic](https://github.com/antonio2368)).
* An option to display partial result on cancel: Added query setting `partial_result_on_first_cancel` allowing the canceled query (e.g. due to Ctrl-C) to return a partial result. [#45689](https://github.com/ClickHouse/ClickHouse/pull/45689) ([Alexey Perevyshin](https://github.com/alexX512)).
* Added support of arbitrary tables engines for temporary tables (except for Replicated and KeeperMap engines). Close [#31497](https://github.com/ClickHouse/ClickHouse/issues/31497). [#46071](https://github.com/ClickHouse/ClickHouse/pull/46071) ([Roman Vasin](https://github.com/rvasin)).
* Add support for replication of user-defined SQL functions using a centralized storage in Keeper. [#46085](https://github.com/ClickHouse/ClickHouse/pull/46085) ([Aleksei Filatov](https://github.com/aalexfvk)).
* Add support for replication of user-defined SQL functions using centralized storage in Keeper. [#46085](https://github.com/ClickHouse/ClickHouse/pull/46085) ([Aleksei Filatov](https://github.com/aalexfvk)).
* Implement `system.server_settings` (similar to `system.settings`), which will contain server configurations. [#46550](https://github.com/ClickHouse/ClickHouse/pull/46550) ([pufit](https://github.com/pufit)).
* Support for `UNDROP TABLE` query. Closes [#46811](https://github.com/ClickHouse/ClickHouse/issues/46811). [#47241](https://github.com/ClickHouse/ClickHouse/pull/47241) ([chen](https://github.com/xiedeyantu)).
* Allow separate grants for named collections (e.g. to be able to give `SHOW/CREATE/ALTER/DROP named collection` access only to certain collections, instead of all at once). Closes [#40894](https://github.com/ClickHouse/ClickHouse/issues/40894). Add new access type `NAMED_COLLECTION_CONTROL` which is not given to default user unless explicitly added to user config (is required to be able to do `GRANT ALL`), also `show_named_collections` is no longer obligatory to be manually specified for default user to be able to have full access rights as was in 23.2. [#46241](https://github.com/ClickHouse/ClickHouse/pull/46241) ([Kseniia Sumarokova](https://github.com/kssenii)).

[#46241](https://github.com/ClickHouse/ClickHouse/pull/46241) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Allow nested custom disks. Previously custom disks supported only flat disk structure. [#47106](https://github.com/ClickHouse/ClickHouse/pull/47106) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Intruduce a function `widthBucket` (with a `WIDTH_BUCKET` alias for compatibility). [#42974](https://github.com/ClickHouse/ClickHouse/issues/42974). [#46790](https://github.com/ClickHouse/ClickHouse/pull/46790) ([avoiderboi](https://github.com/avoiderboi)).
* Add new function `parseDateTime`/`parseDateTimeInJodaSyntax` according to specified format string. parseDateTime parses string to datetime in MySQL syntax, parseDateTimeInJodaSyntax parses in Joda syntax. [#46815](https://github.com/ClickHouse/ClickHouse/pull/46815) ([李扬](https://github.com/taiyang-li)).
* Use `dummy UInt8` for default structure of table function `null`. Closes [#46930](https://github.com/ClickHouse/ClickHouse/issues/46930). [#47006](https://github.com/ClickHouse/ClickHouse/pull/47006) ([flynn](https://github.com/ucasfl)).

* Support for date format with a comma, like `Dec 15, 2021` in the `parseDateTimeBestEffort` function. Closes [#46816](https://github.com/ClickHouse/ClickHouse/issues/46816). [#47071](https://github.com/ClickHouse/ClickHouse/pull/47071) ([chen](https://github.com/xiedeyantu)).
* Add settings `http_wait_end_of_query` and `http_response_buffer_size` that corresponds to URL params `wait_end_of_query` and `buffer_size` for HTTP interface. This allows to change these settings in the profiles. [#47108](https://github.com/ClickHouse/ClickHouse/pull/47108) ([Vladimir C](https://github.com/vdimir)).
* Add settings `http_wait_end_of_query` and `http_response_buffer_size` that corresponds to URL params `wait_end_of_query` and `buffer_size` for the HTTP interface. This allows changing these settings in the profiles. [#47108](https://github.com/ClickHouse/ClickHouse/pull/47108) ([Vladimir C](https://github.com/vdimir)).
* Add `system.dropped_tables` table that shows tables that were dropped from `Atomic` databases but were not completely removed yet. [#47364](https://github.com/ClickHouse/ClickHouse/pull/47364) ([chen](https://github.com/xiedeyantu)).
* Add `INSTR` as alias of `positionCaseInsensitive` for MySQL compatibility. Closes [#47529](https://github.com/ClickHouse/ClickHouse/issues/47529). [#47535](https://github.com/ClickHouse/ClickHouse/pull/47535) ([flynn](https://github.com/ucasfl)).
* Added `toDecimalString` function allowing to convert numbers to string with fixed precision. [#47838](https://github.com/ClickHouse/ClickHouse/pull/47838) ([Andrey Zvonov](https://github.com/zvonand)).
* Add a merge tree setting `max_number_of_mutations_for_replica`. It limits the number of part mutations per replica to the specified amount. Zero means no limit on the number of mutations per replica (the execution can still be constrained by other settings). [#48047](https://github.com/ClickHouse/ClickHouse/pull/48047) ([Vladimir C](https://github.com/vdimir)).
* Add Map-related function `mapFromArrays`, which allows us to create map from a pair of arrays. [#31125](https://github.com/ClickHouse/ClickHouse/pull/31125) ([李扬](https://github.com/taiyang-li)).
* Allow control compression in Parquet/ORC/Arrow output formats, support more compression for input formats. This closes [#13541](https://github.com/ClickHouse/ClickHouse/issues/13541). [#47114](https://github.com/ClickHouse/ClickHouse/pull/47114) ([Kruglov Pavel](https://github.com/Avogar)).
* Add the Map-related function `mapFromArrays`, which allows the creation of a map from a pair of arrays. [#31125](https://github.com/ClickHouse/ClickHouse/pull/31125) ([李扬](https://github.com/taiyang-li)).
* Allow control of compression in Parquet/ORC/Arrow output formats, adds support for more compression input formats. This closes [#13541](https://github.com/ClickHouse/ClickHouse/issues/13541). [#47114](https://github.com/ClickHouse/ClickHouse/pull/47114) ([Kruglov Pavel](https://github.com/Avogar)).
* Add SSL User Certificate authentication to the native protocol. Closes [#47077](https://github.com/ClickHouse/ClickHouse/issues/47077). [#47596](https://github.com/ClickHouse/ClickHouse/pull/47596) ([Nikolay Degterinsky](https://github.com/evillique)).
* Add *OrNull() and *OrZero() variants for `parseDateTime`, add alias `str_to_date` for MySQL parity. [#48000](https://github.com/ClickHouse/ClickHouse/pull/48000) ([Robert Schulze](https://github.com/rschu1ze)).
* Added operator `REGEXP` (similar to operators "LIKE", "IN", "MOD" etc.) for better compatibility with MySQL [#47869](https://github.com/ClickHouse/ClickHouse/pull/47869) ([Robert Schulze](https://github.com/rschu1ze)).
#### Performance Improvement
* Marks in memory are now compressed, using 3-6x less memory. [#47290](https://github.com/ClickHouse/ClickHouse/pull/47290) ([Michael Kolupaev](https://github.com/al13n321)).
* Backups for large numbers of files were unbelievably slow in previous versions. Not anymore. Now they are unbelievably fast. [#47251](https://github.com/ClickHouse/ClickHouse/pull/47251) ([Alexey Milovidov](https://github.com/alexey-milovidov)). Introduced a separate thread pool for backup's IO operations. This will allow to scale it independently of other pools and increase performance. [#47174](https://github.com/ClickHouse/ClickHouse/pull/47174) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)). Use MultiRead request and retries for collecting metadata at final stage of backup processing. [#47243](https://github.com/ClickHouse/ClickHouse/pull/47243) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)). If a backup and restoring data are both in S3 then server-side copy should be used from now on. [#47546](https://github.com/ClickHouse/ClickHouse/pull/47546) ([Vitaly Baranov](https://github.com/vitlibar)).

[#47546](https://github.com/ClickHouse/ClickHouse/pull/47546) ([Vitaly Baranov](https://github.com/vitlibar)).
* Fixed excessive reading in queries with `FINAL`. [#47801](https://github.com/ClickHouse/ClickHouse/pull/47801) ([Nikita Taranov](https://github.com/nickitat)).

# 2023 Changelog
### ClickHouse release v23.3.1.2823-lts (46e85357ce2) FIXME as compared to v23.2.1.2537-stable (52bf836e03a)
#### Backward Incompatible Change
* Relax symbols that are allowed in URL authority in *domain*RFC()/netloc(). [#46841](https://github.com/ClickHouse/ClickHouse/pull/46841) ([Azat Khuzhin](https://github.com/azat)).
* Prohibit create tables based on KafkaEngine with DEFAULT/EPHEMERAL/ALIAS/MATERIALIZED statements for columns. [#47138](https://github.com/ClickHouse/ClickHouse/pull/47138) ([Aleksandr Musorin](https://github.com/AVMusorin)).
* An "asynchronous connection drain" feature is removed. Related settings and metrics are removed as well. It was an internal feature, so the removal should not affect users who had never heard about that feature. [#47486](https://github.com/ClickHouse/ClickHouse/pull/47486) ([Alexander Tokmakov](https://github.com/tavplubix)).
* Support 256-bit Decimal data type (more than 38 digits) in `arraySum`/`Min`/`Max`/`Avg`/`Product`, `arrayCumSum`/`CumSumNonNegative`, `arrayDifference`, array construction, IN operator, query parameters, `groupArrayMovingSum`, statistical functions, `min`/`max`/`any`/`argMin`/`argMax`, PostgreSQL wire protocol, MySQL table engine and function, `sumMap`, `mapAdd`, `mapSubtract`, `arrayIntersect`. Add support for big integers in `arrayIntersect`. Statistical aggregate functions involving moments (such as `corr` or various `TTest`s) will use `Float64` as their internal representation (they were using `Decimal128` before this change, but it was pointless), and these functions can return `nan` instead of `inf` in case of infinite variance. Some functions were allowed on `Decimal256` data types but returned `Decimal128` in previous versions - now it is fixed. This closes [#47569](https://github.com/ClickHouse/ClickHouse/issues/47569). This closes [#44864](https://github.com/ClickHouse/ClickHouse/issues/44864). This closes [#28335](https://github.com/ClickHouse/ClickHouse/issues/28335). [#47594](https://github.com/ClickHouse/ClickHouse/pull/47594) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Make backup_threads/restore_threads server settings. [#47881](https://github.com/ClickHouse/ClickHouse/pull/47881) ([Azat Khuzhin](https://github.com/azat)).
* Fix the isIPv6String function which could have outputted a false positive result in the case of an incorrect IPv6 address. For example `1234::1234:` was considered a valid IPv6 address. [#47895](https://github.com/ClickHouse/ClickHouse/pull/47895) ([Nikolay Degterinsky](https://github.com/evillique)).
#### New Feature
* Add new mode for splitting the work on replicas using settings `parallel_replicas_custom_key` and `parallel_replicas_custom_key_filter_type`. If the cluster consists of a single shard with multiple replicas, up to `max_parallel_replicas` will be randomly picked and turned into shards. For each shard, a corresponding filter is added to the query on the initiator before being sent to the shard. If the cluster consists of multiple shards, it will behave the same as `sample_key` but with the possibility to define an arbitrary key. [#45108](https://github.com/ClickHouse/ClickHouse/pull/45108) ([Antonio Andelic](https://github.com/antonio2368)).
* Added query setting `partial_result_on_first_cancel` allowing the canceled query (e.g. due to Ctrl-C) to return a partial result. [#45689](https://github.com/ClickHouse/ClickHouse/pull/45689) ([Alexey Perevyshin](https://github.com/alexX512)).
* Added support of arbitrary tables engines for temporary tables except for Replicated and KeeperMap engines. Partially close [#31497](https://github.com/ClickHouse/ClickHouse/issues/31497). [#46071](https://github.com/ClickHouse/ClickHouse/pull/46071) ([Roman Vasin](https://github.com/rvasin)).
* Add replication of user-defined SQL functions using ZooKeeper. [#46085](https://github.com/ClickHouse/ClickHouse/pull/46085) ([Aleksei Filatov](https://github.com/aalexfvk)).
* Implement `system.server_settings` (similar to `system.settings`), which will contain server configurations. [#46550](https://github.com/ClickHouse/ClickHouse/pull/46550) ([pufit](https://github.com/pufit)).
* Intruduce a function `WIDTH_BUCKET`. [#42974](https://github.com/ClickHouse/ClickHouse/issues/42974). [#46790](https://github.com/ClickHouse/ClickHouse/pull/46790) ([avoiderboi](https://github.com/avoiderboi)).
* Add new function parseDateTime/parseDateTimeInJodaSyntax according to specified format string. parseDateTime parses string to datetime in MySQL syntax, parseDateTimeInJodaSyntax parses in Joda syntax. [#46815](https://github.com/ClickHouse/ClickHouse/pull/46815) ([李扬](https://github.com/taiyang-li)).
* Use `dummy UInt8` for default structure of table function `null`. Closes [#46930](https://github.com/ClickHouse/ClickHouse/issues/46930). [#47006](https://github.com/ClickHouse/ClickHouse/pull/47006) ([flynn](https://github.com/ucasfl)).
* Dec 15, 2021 support for parseDateTimeBestEffort function. closes [#46816](https://github.com/ClickHouse/ClickHouse/issues/46816). [#47071](https://github.com/ClickHouse/ClickHouse/pull/47071) ([chen](https://github.com/xiedeyantu)).
* Add function ULIDStringToDateTime(). Closes [#46945](https://github.com/ClickHouse/ClickHouse/issues/46945). [#47087](https://github.com/ClickHouse/ClickHouse/pull/47087) ([Nikolay Degterinsky](https://github.com/evillique)).
* Add settings `http_wait_end_of_query` and `http_response_buffer_size` that corresponds to URL params `wait_end_of_query` and `buffer_size` for HTTP interface. [#47108](https://github.com/ClickHouse/ClickHouse/pull/47108) ([Vladimir C](https://github.com/vdimir)).
* Support for `UNDROP TABLE` query. Closes [#46811](https://github.com/ClickHouse/ClickHouse/issues/46811). [#47241](https://github.com/ClickHouse/ClickHouse/pull/47241) ([chen](https://github.com/xiedeyantu)).
* Add `system.marked_dropped_tables` table that shows tables that were dropped from `Atomic` databases but were not completely removed yet. [#47364](https://github.com/ClickHouse/ClickHouse/pull/47364) ([chen](https://github.com/xiedeyantu)).
* Add `INSTR` as alias of `positionCaseInsensitive` for MySQL compatibility. Closes [#47529](https://github.com/ClickHouse/ClickHouse/issues/47529). [#47535](https://github.com/ClickHouse/ClickHouse/pull/47535) ([flynn](https://github.com/ucasfl)).
* Added `toDecimalString` function allowing to convert numbers to string with fixed precision. [#47838](https://github.com/ClickHouse/ClickHouse/pull/47838) ([Andrey Zvonov](https://github.com/zvonand)).
* Added operator "REGEXP" (similar to operators "LIKE", "IN", "MOD" etc.) for better compatibility with MySQL. [#47869](https://github.com/ClickHouse/ClickHouse/pull/47869) ([Robert Schulze](https://github.com/rschu1ze)).
* Allow executing reading pipeline for DIRECT dictionary with CLICKHOUSE source in multiple threads. To enable set `dictionary_use_async_executor=1` in `SETTINGS` section for source in `CREATE DICTIONARY` statement. [#47986](https://github.com/ClickHouse/ClickHouse/pull/47986) ([Vladimir C](https://github.com/vdimir)).
* Add merge tree setting `max_number_of_mutatuins_for_replica`. It limit the number of part mutations per replica to the specified amount. Zero means no limit on the number of mutations per replica (the execution can still be constrained by other settings). [#48047](https://github.com/ClickHouse/ClickHouse/pull/48047) ([Vladimir C](https://github.com/vdimir)).
#### Performance Improvement
* Optimize one nullable key aggregate performance. [#45772](https://github.com/ClickHouse/ClickHouse/pull/45772) ([LiuNeng](https://github.com/liuneng1994)).
* Implemented lowercase tokenbf_v1 index utilization for hasTokenOrNull, hasTokenCaseInsensitive and hasTokenCaseInsensitiveOrNull. [#46252](https://github.com/ClickHouse/ClickHouse/pull/46252) ([ltrk2](https://github.com/ltrk2)).
* Optimize the generic SIMD StringSearcher by searching first two chars. [#46289](https://github.com/ClickHouse/ClickHouse/pull/46289) ([Jiebin Sun](https://github.com/jiebinn)).
* System.detached_parts could be significant large. - added several sources with respects block size limitation - in each block iothread pool is used to calculate part size, ie to make syscalls in parallel. [#46624](https://github.com/ClickHouse/ClickHouse/pull/46624) ([Sema Checherinda](https://github.com/CheSema)).
* Increase the default value of `max_replicated_merges_in_queue` for ReplicatedMergeTree tables from 16 to 1000. It allows faster background merge operation on clusters with a very large number of replicas, such as clusters with shared storage in ClickHouse Cloud. [#47050](https://github.com/ClickHouse/ClickHouse/pull/47050) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Backups for large numbers of files were unbelievably slow in previous versions. [#47251](https://github.com/ClickHouse/ClickHouse/pull/47251) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Support filter push down to left table for JOIN with StorageJoin, StorageDictionary, StorageEmbeddedRocksDB. [#47280](https://github.com/ClickHouse/ClickHouse/pull/47280) ([Maksim Kita](https://github.com/kitaisreal)).
* Marks in memory are now compressed, using 3-6x less memory. [#47290](https://github.com/ClickHouse/ClickHouse/pull/47290) ([Michael Kolupaev](https://github.com/al13n321)).
* Updated copier to use group by instead of distinct to get list of partitions. For large tables this reduced the select time from over 500s to under 1s. [#47386](https://github.com/ClickHouse/ClickHouse/pull/47386) ([Clayton McClure](https://github.com/cmcclure-twilio)).
* Address https://github.com/clickhouse/clickhouse/issues/46453. bisect marked https://github.com/clickhouse/clickhouse/pull/35525 as the bad changed. this pr looks to reverse the changes in that pr. [#47544](https://github.com/ClickHouse/ClickHouse/pull/47544) ([Ongkong](https://github.com/ongkong)).
* Fixed excessive reading in queries with `FINAL`. [#47801](https://github.com/ClickHouse/ClickHouse/pull/47801) ([Nikita Taranov](https://github.com/nickitat)).
* Setting `max_final_threads` would be set to number of cores at server startup (by the same algorithm as we use for `max_threads`). This improves concurrency of `final` execution on servers with high number of CPUs. [#47915](https://github.com/ClickHouse/ClickHouse/pull/47915) ([Nikita Taranov](https://github.com/nickitat)).
* Avoid breaking batches on read requests to improve performance. [#47978](https://github.com/ClickHouse/ClickHouse/pull/47978) ([Antonio Andelic](https://github.com/antonio2368)).
#### Improvement
* Add map related functions: mapFromArrays, which allows us to create map from a pair of arrays. [#31125](https://github.com/ClickHouse/ClickHouse/pull/31125) ([李扬](https://github.com/taiyang-li)).
* Rewrite distributed sends to avoid using filesystem as a queue, use in-memory queue instead. [#45491](https://github.com/ClickHouse/ClickHouse/pull/45491) ([Azat Khuzhin](https://github.com/azat)).
* Allow separate grants for named collections (e.g. to be able to give `SHOW/CREATE/ALTER/DROP named collection` access only to certain collections, instead of all at once). Closes [#40894](https://github.com/ClickHouse/ClickHouse/issues/40894). Add new access type `NAMED_COLLECTION_CONTROL` which is not given to default user unless explicitly added to user config (is required to be able to do `GRANT ALL`), also `show_named_collections` is no longer obligatory to be manually specified for default user to be able to have full access rights as was in 23.2. [#46241](https://github.com/ClickHouse/ClickHouse/pull/46241) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Now `X-ClickHouse-Query-Id` and `X-ClickHouse-Timezone` headers are added to response in all queries via http protocol. Previously it was done only for `SELECT` queries. [#46364](https://github.com/ClickHouse/ClickHouse/pull/46364) ([Anton Popov](https://github.com/CurtizJ)).
* Support for connection to a replica set via a URI with a host:port enum and support for the readPreference option in MongoDB dictionaries. Example URI: mongodb://db0.example.com:27017,db1.example.com:27017,db2.example.com:27017/?replicaSet=myRepl&readPreference=primary. [#46524](https://github.com/ClickHouse/ClickHouse/pull/46524) ([artem-yadr](https://github.com/artem-yadr)).
* Re-implement projection analysis on top of query plan. Added setting `query_plan_optimize_projection=1` to switch between old and new version. Fixes [#44963](https://github.com/ClickHouse/ClickHouse/issues/44963). [#46537](https://github.com/ClickHouse/ClickHouse/pull/46537) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
* Use parquet format v2 instead of v1 in output format by default. Add setting `output_format_parquet_version` to control parquet version, possible values `v1_0`, `v2_4`, `v2_6`, `v2_latest` (default). [#46617](https://github.com/ClickHouse/ClickHouse/pull/46617) ([Kruglov Pavel](https://github.com/Avogar)).
* Not for changelog - part of [#42648](https://github.com/ClickHouse/ClickHouse/issues/42648). [#46632](https://github.com/ClickHouse/ClickHouse/pull/46632) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
* Allow to ignore errors while pushing to MATERILIZED VIEW (add new setting `materialized_views_ignore_errors`, by default to `false`, but it is set to `true` for flushing logs to `system.*_log` tables unconditionally). [#46658](https://github.com/ClickHouse/ClickHouse/pull/46658) ([Azat Khuzhin](https://github.com/azat)).
* Enable input_format_json_ignore_unknown_keys_in_named_tuple by default. [#46742](https://github.com/ClickHouse/ClickHouse/pull/46742) ([Kruglov Pavel](https://github.com/Avogar)).
* It is now possible using new configuration syntax to configure Kafka topics with periods in their name. [#46752](https://github.com/ClickHouse/ClickHouse/pull/46752) ([Robert Schulze](https://github.com/rschu1ze)).
* Fix heuristics that check hyperscan patterns for problematic repeats. [#46819](https://github.com/ClickHouse/ClickHouse/pull/46819) ([Robert Schulze](https://github.com/rschu1ze)).
* Don't report ZK node exists to system.errors when a block was created concurrently by a different replica. [#46820](https://github.com/ClickHouse/ClickHouse/pull/46820) ([Raúl Marín](https://github.com/Algunenano)).
* Allow PREWHERE for Merge with different DEFAULT expression for column. [#46831](https://github.com/ClickHouse/ClickHouse/pull/46831) ([Azat Khuzhin](https://github.com/azat)).
* Increase the limit for opened files in `clickhouse-local`. It will be able to read from `web` tables on servers with a huge number of CPU cores. Do not back off reading from the URL table engine in case of too many opened files. This closes [#46852](https://github.com/ClickHouse/ClickHouse/issues/46852). [#46853](https://github.com/ClickHouse/ClickHouse/pull/46853) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Exceptions thrown when numbers cannot be parsed now have an easier-to-read exception message. [#46917](https://github.com/ClickHouse/ClickHouse/pull/46917) ([Robert Schulze](https://github.com/rschu1ze)).

## Accessing public buckets
ClickHouse tries to fetch credentials from many different types of sources.
Sometimes, it can produce problems when accessing some buckets that are public causing the client to return `403` error code.
This issue can be avoided by using `NOSIGN` keyword, forcing the client to ignore all the credentials, and not sign the requests.

CREATE TABLE big_table (name String, value UInt32)

4. Open a new tab in the SQL Console of ClickHouse Cloud (or a new `clickhouse-client` window) and watch the count increase. It will take a while to insert 4.56B rows, depending on your server resources. (Withtout any tweaking of settings, it takes about 4.5 hours.)
Some comments about our `INSERT` command:
- The `parseDateTimeBestEffortUSOrZero` function is handy when the incoming date fields may not be in the proper format. If `fetch_date` does not get parsed properly, it will be set to `0`
- The `upload_date` column contains valid dates, but it also contains strings like "4 hours ago" - which is certainly not a valid date. We decided to store the original value in `upload_date_str` and attempt to parse it with `toDate(parseDateTimeBestEffortUSOrZero(upload_date::String))`. If the parsing fails we just get `0`
- We used `ifNull` to avoid getting `NULL` values in our table. If an incoming value is `NULL`, the `ifNull` function is setting the value to an empty string
- It takes a long time to download the data, so we added a `SETTINGS` clause to spread out the work over more threads while making sure the block sizes stayed fairly large

Entries in the query cache become stale after a certain time period (time-to-live). By default, this period is 60 seconds but a different
value can be specified at session, profile or query level using setting [query_cache_ttl](settings/settings.md#query-cache-ttl).
Entries in the query cache are compressed by default. This reduces the overall memory consumption at the cost of slower writes into / reads
from the query cache. To disable compression, use setting [query_cache_compress_entries](settings/settings.md#query-cache-compress-entries).
ClickHouse reads table data in blocks of [max_block_size](settings/settings.md#settings-max_block_size) rows. Due to filtering, aggregation,
etc., result blocks are typically much smaller than 'max_block_size' but there are also cases where they are much bigger. Setting
[query_cache_squash_partial_results](settings/settings.md#query-cache-squash-partial-results) (enabled by default) controls if result blocks
are squashed (if they are tiny) or split (if they are large) into blocks of 'max_block_size' size before insertion into the query result
cache. This reduces performance of writes into the query cache but improves compression rate of cache entries and provides more natural
block granularity when query results are later served from the query cache.
As a result, the query cache stores for each query multiple (partial)
result blocks. While this behavior is a good default, it can be suppressed using setting
[query_cache_squash_partial_query_results](settings/settings.md#query-cache-squash-partial-query-results).
Also, results of queries with non-deterministic functions such as `rand()` and `now()` are not cached. This can be overruled using
setting [query_cache_store_results_of_queries_with_nondeterministic_functions](settings/settings.md#query-cache-store-results-of-queries-with-nondeterministic-functions).

This setting is also could be applied at server startup from the `default` profile configuration for backward compatibility at the ClickHouse server start. You can only increase the number of threads at runtime. To lower the number of threads you have to restart the server. By adjusting this setting, you manage CPU and disk load.

Merge reads rows from parts in blocks of `merge_max_block_size` rows, then merges and writes the result into a new part. The read block is placed in RAM, so `merge_max_block_size` affects the size of the RAM required for the merge. Thus, merges can consume a large amount of RAM for tables with very wide rows (if the average row size is 100kb, then when merging 10 parts, (100kb * 10 * 8192) = ~ 8GB of RAM). By decreasing `merge_max_block_size`, you can reduce the amount of RAM required for a merge but slow down a merge.

The `clickhouse-local` program enables you to perform fast processing on local files, without having to deploy and configure the ClickHouse server. It accepts data that represent tables and queries them using [ClickHouse SQL dialect](../../sql-reference/index.md). `clickhouse-local` uses the same core as ClickHouse server, so it supports most of the features and the same set of formats and table engines.
By default `clickhouse-local` has access to data on the same host, and it does not depend on the server's configuration. It also supports loading server configuration using `--config-file` argument. For temporary data, a unique temporary data directory is created by default.
## Download clickhouse-local
`clickhouse-local` is executed using the same `clickhouse` binary that runs the ClickHouse server and `clickhouse-client`. The easiest way to download the latest version is with the following command:
```bash
curl https://clickhouse.com/ | sh
```
:::note
The binary you just downloaded can run all sorts of ClickHouse tools and utilities. If you want to run ClickHouse as a database server, check out the [Quick Start](../../quick-start.mdx).
:::
## Query data in a CSV file using SQL
A common use of `clickhouse-local` is to run ad-hoc queries on files: where you don't have to insert the data into a table. `clickhouse-local` can stream the data from a file into a temporary table and execute your SQL.
If the file is sitting on the same machine as `clickhouse-local`, use the `file` table engine. The following `reviews.tsv` file contains a sampling of Amazon product reviews:
```bash
./clickhouse local -q "SELECT * FROM file('reviews.tsv')"
```
ClickHouse knows the file uses a tab-separated format from filename extension. If you need to explicitly specify the format, simply add one of the [many ClickHouse input formats](../../interfaces/formats.md):
```bash
./clickhouse local -q "SELECT * FROM file('reviews.tsv', 'TabSeparated')"
```
The `file` table function creates a table, and you can use `DESCRIBE` to see the inferred schema:
```bash
./clickhouse local -q "DESCRIBE file('reviews.tsv')"
```
```response
marketplace Nullable(String)
customer_id Nullable(Int64)
review_id Nullable(String)
product_id Nullable(String)
product_parent Nullable(Int64)

max(star_rating)

```

## Query data in a Parquet file in AWS S3
If you have a file in S3, use `clickhouse-local` and the `s3` table function to query the file in place (without inserting the data into a ClickHouse table). We have a file named `house_0.parquet` in a public bucket that contains home prices of property sold in the United Kingdom. Let's see how many rows it has:
```bash
./clickhouse local -q "
SELECT count()
FROM s3('https://datasets-documentation.s3.eu-west-3.amazonaws.com/house_parquet/house_0.parquet')"
```
The file has 2.7M rows:
```response
2772030
```
It's always useful to see what the inferred schema that ClickHouse determines from the file:
```bash
./clickhouse local -q "DESCRIBE s3('https://datasets-documentation.s3.eu-west-3.amazonaws.com/house_parquet/house_0.parquet')"
```
```response

# quantileApprox
Computes the [quantile](https://en.wikipedia.org/wiki/Quantile) of a numeric data sequence using the [Greenwald-Khanna](http://infolab.stanford.edu/~datar/courses/cs361a/papers/quantiles.pdf) algorithm. The Greenwald-Khanna algorithm is an algorithm used to compute quantiles on a stream of data in a highly efficient manner. It was introduced by Michael Greenwald and Sanjeev Khanna in 2001. It is widely used in databases and big data systems where computing accurate quantiles on a large stream of data in real-time is necessary. The algorithm is highly efficient, taking only O(log n) space and O(log log n) time per item (where n is the size of the input). It is also highly accurate, providing an approximate quantile value with high probability.
`quantileApprox` is different from other quantile functions in ClickHouse, because it enables user to control the accuracy of the approximate quantile result.
**Syntax**
``` sql
quantileApprox(accuracy, level)(expr)
```
Alias: `medianApprox`.
**Arguments**
- `accuracy` — Accuracy of quantile. Constant positive integer. Larger accuracy value means less error. For example, if the accuracy argument is set to 100, the computed quantile will have an error no greater than 1% with high probability. There is a trade-off between the accuracy of the computed quantiles and the computational complexity of the algorithm. A larger accuracy requires more memory and computational resources to compute the quantile accurately, while a smaller accuracy argument allows for a faster and more memory-efficient computation but with a slightly lower accuracy.
- `level` — Level of quantile. Optional parameter. Constant floating-point number from 0 to 1. Default value: 0.5. At `level=0.5` the function calculates [median](https://en.wikipedia.org/wiki/Median).
- `expr` — Expression over the column values resulting in numeric [data types](../../../sql-reference/data-types/index.md#data_types), [Date](../../../sql-reference/data-types/date.md) or [DateTime](../../../sql-reference/data-types/datetime.md).
**Returned value**
- Quantile of the specified level and accuracy.
Type:
- [Float64](../../../sql-reference/data-types/float.md) for numeric data type input.
- [Date](../../../sql-reference/data-types/date.md) if input values have the `Date` type.
- [DateTime](../../../sql-reference/data-types/datetime.md) if input values have the `DateTime` type.
**Example**
``` sql
SELECT quantileApprox(1, 0.25)(number + 1)
FROM numbers(1000)
┌─quantileApprox(1, 0.25)(plus(number, 1))─┐

## quantilesApprox
`quantilesApprox` works similarly with `quantileApprox` but allows us to calculate quantities at different levels simultaneously and returns an array.
**Syntax**
``` sql
quantilesApprox(accuracy, level1, level2, ...)(expr)
```
**Returned value**
- [Array](../../../sql-reference/data-types/array.md) of quantiles of the specified levels.
Type of array values:
- [Float64](../../../sql-reference/data-types/float.md) for numeric data type input.
- [Date](../../../sql-reference/data-types/date.md) if input values have the `Date` type.
- [DateTime](../../../sql-reference/data-types/datetime.md) if input values have the `DateTime` type.

## mapFromArrays
Merges an [Array](../../sql-reference/data-types/array.md) of keys and an [Array](../../sql-reference/data-types/array.md) of values into a [Map(key, value)](../../sql-reference/data-types/map.md).
Merges an [Array](../../sql-reference/data-types/array.md) of keys and an [Array](../../sql-reference/data-types/array.md) of values into a [Map(key, value)](../../sql-reference/data-types/map.md). Notice that the second argument could also be a [Map](../../sql-reference/data-types/map.md), thus it is casted to an Array when executing.
The function is a more convenient alternative to `CAST((key_array, value_array), 'Map(key_type, value_type)')`. For example, instead of writing `CAST((['aa', 'bb'], [4, 5]), 'Map(String, UInt32)')`, you can write `mapFromArrays(['aa', 'bb'], [4, 5])`.

## SHOW COLUMNS
Displays a list of columns
```sql
SHOW [EXTENDED] [FULL] COLUMNS {FROM | IN} <table> [{FROM | IN} <db>] [{[NOT] {LIKE | ILIKE} '<pattern>' | WHERE <expr>}] [LIMIT <N>] [INTO
OUTFILE <filename>] [FORMAT <format>]
```
The database and table name can be specified in abbreviated form as `<db>.<table>`, i.e. `FROM tab FROM db` and `FROM db.tab` are
equivalent. If no database is specified, the query returns the list of columns from the current database.
The optional keyword `EXTENDED` currently has no effect, it only exists for MySQL compatibility.
The optional keyword `FULL` causes the output to include the collation, comment and privilege columns.
`SHOW COLUMNS` produces a result table with the following structure:
- field - The name of the column (String)
- type - The column data type (String)
- null - If the column data type is Nullable (UInt8)
- key - `PRI` if the column is part of the primary key, `SOR` if the column is part of the sorting key, empty otherwise (String)
- default - Default expression of the column if it is of type `ALIAS`, `DEFAULT`, or `MATERIALIZED`, otherwise `NULL`. (Nullable(String))
- extra - Additional information, currently unused (String)
- collation - (only if `FULL` keyword was specified) Collation of the column, always `NULL` because ClickHouse has no per-column collations (Nullable(String))
- comment - (only if `FULL` keyword was specified) Comment on the column (String)
- privilege - (only if `FULL` keyword was specified) The privilege you have on this column, currently not available (String)

ClickHouse tries to fetch credentials from many different types of sources.
Sometimes, it can produce problems when accessing some buckets that are public causing the client to return `403` error code.
This issue can be avoided by using `NOSIGN` keyword, forcing the client to ignore all the credentials, and not sign the requests.

// Merge the two buffers.
// The GK algorithm is a bit unclear about it, but we need to adjust the statistics during the
// merging. The main idea is that samples that come from one side will suffer from the lack of
// precision of the other.
// As a concrete example, take two QuantileSummaries whose samples (value, g, delta) are:
// `a = [(0, 1, 0), (20, 99, 0)]` and `b = [(10, 1, 0), (30, 49, 0)]`
// This means `a` has 100 values, whose minimum is 0 and maximum is 20,
// while `b` has 50 values, between 10 and 30.
// The resulting samples of the merge will be:
// a+b = [(0, 1, 0), (10, 1, ??), (20, 99, ??), (30, 49, 0)]
// The values of `g` do not change, as they represent the minimum number of values between two
// consecutive samples. The values of `delta` should be adjusted, however.
// Take the case of the sample `10` from `b`. In the original stream, it could have appeared
// right after `0` (as expressed by `g=1`) or right before `20`, so `delta=99+0-1=98`.
// In the GK algorithm's style of working in terms of maximum bounds, one can observe that the
// maximum additional uncertainty over samples coming from `b` is `max(g_a + delta_a) =
// floor(2 * eps_a * n_a)`. Likewise, additional uncertainty over samples from `a` is
// `floor(2 * eps_b * n_b)`.
// Only samples that interleave the other side are affected. That means that samples from
// one side that are lesser (or greater) than all samples from the other side are just copied
// unmodified.
// If the merging instances have different `relativeError`, the resulting instance will carry
// the largest one: `eps_ab = max(eps_a, eps_b)`.
// The main invariant of the GK algorithm is kept:
// `max(g_ab + delta_ab) <= floor(2 * eps_ab * (n_a + n_b))` since
// `max(g_ab + delta_ab) <= floor(2 * eps_a * n_a) + floor(2 * eps_b * n_b)`
// Finally, one can see how the `insert(x)` operation can be expressed as `merge([(x, 1, 0])`
