|
||||
|
||||
#### Experimental Feature
|
||||
|
||||
* Added support for transactions for simple `MergeTree` tables. This feature is highly experimental and not recommended for production. Part of [#22086](https://github.com/ClickHouse/ClickHouse/issues/22086). [#24258](https://github.com/ClickHouse/ClickHouse/pull/24258) ([tavplubix](https://github.com/tavplubix)).
|
||||
* Support schema inference for type `Object` in format `JSONEachRow`. Allow to convert columns of type `Map` to columns of type `Object`. [#35629](https://github.com/ClickHouse/ClickHouse/pull/35629) ([Anton Popov](https://github.com/CurtizJ)).
|
||||
* Allow to write remote FS cache on all write operations. Add `system.remote_filesystem_cache` table. Add `drop remote filesystem cache` query. Add introspection for s3 metadata with `system.remote_data_paths` table. Closes [#34021](https://github.com/ClickHouse/ClickHouse/issues/34021). Add cache option for merges by adding mode `read_from_filesystem_cache_if_exists_otherwise_bypass_cache` (turned on by default for merges and can also be turned on by query setting with the same name). Rename cache related settings (`remote_fs_enable_cache -> enable_filesystem_cache`, etc). [#35475](https://github.com/ClickHouse/ClickHouse/pull/35475) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
* An option to store parts metadata in RocksDB. Speed up parts loading process of MergeTree to accelerate starting up of clickhouse-server. With this improvement, clickhouse-server was able to decrease starting up time from 75 minutes to 20 seconds, with 700k mergetree parts. [#32928](https://github.com/ClickHouse/ClickHouse/pull/32928) ([李扬](https://github.com/taiyang-li)).

|
||||
|
||||
* A new query plan optimization. Evaluate functions after `ORDER BY` when possible. As an example, for a query `SELECT sipHash64(number) FROM numbers(1e8) ORDER BY number LIMIT 5`, function `sipHash64` would be evaluated after `ORDER BY` and `LIMIT`, which gives ~20x speed up. [#35623](https://github.com/ClickHouse/ClickHouse/pull/35623) ([Nikita Taranov](https://github.com/nickitat)).
|
||||
* Sizes of hash tables used during aggregation now collected and used in later queries to avoid hash tables resizes. [#33439](https://github.com/ClickHouse/ClickHouse/pull/33439) ([Nikita Taranov](https://github.com/nickitat)).
|
||||
* Improve performance of `hasAll` function using specializations for SSE and AVX2. Author @youennL-cs. [#35723](https://github.com/ClickHouse/ClickHouse/pull/35723) ([Maksim Kita](https://github.com/kitaisreal)).

|
||||
* Multiple changes to improve ASOF JOIN performance (1.2 - 1.6x as fast). It also adds support to use big integers. [#34733](https://github.com/ClickHouse/ClickHouse/pull/34733) ([Raúl Marín](https://github.com/Algunenano)).
|
||||
* Improve performance of ASOF JOIN if key is native integer. [#35525](https://github.com/ClickHouse/ClickHouse/pull/35525) ([Maksim Kita](https://github.com/kitaisreal)).
|
||||
* Parallelization of multipart upload into S3 storage. [#35343](https://github.com/ClickHouse/ClickHouse/pull/35343) ([Sergei Trifonov](https://github.com/serxa)).
|
||||
* URL storage engine now downloads multiple chunks in parallel if the endpoint supports HTTP Range. Two additional settings were added, `max_download_threads` and `max_download_buffer_size`, which control maximum number of threads a single query can use to download the file and the maximum number of bytes each thread can process. [#35150](https://github.com/ClickHouse/ClickHouse/pull/35150) ([Antonio Andelic](https://github.com/antonio2368)).
|
||||
* Use multiple threads to download objects from S3. Downloading is controllable using `max_download_threads` and `max_download_buffer_size` settings. [#35571](https://github.com/ClickHouse/ClickHouse/pull/35571) ([Antonio Andelic](https://github.com/antonio2368)).

|
||||
* Narrow mutex scope when interacting with HDFS. Related to [#35292](https://github.com/ClickHouse/ClickHouse/issues/35292). [#35646](https://github.com/ClickHouse/ClickHouse/pull/35646) ([shuchaome](https://github.com/shuchaome)).

|
||||
|
||||
|
||||
#### Improvement
|
||||
|
||||
* Multiple improvements for schema inference. Use some tweaks and heuristics to determine numbers, strings, arrays, tuples and maps in CSV, TSV and TSVRaw data formats. Add setting `input_format_csv_use_best_effort_in_schema_inference` for CSV format that enables/disables using these heuristics, if it's disabled, we treat everything as string. Add similar setting `input_format_tsv_use_best_effort_in_schema_inference` for TSV/TSVRaw format. These settings are enabled by default. - Add Maps support for schema inference in Values format. - Fix possible segfault in schema inference in Values format. - Allow to skip columns with unsupported types in Arrow/ORC/Parquet formats. Add corresponding settings for it: `input_format_{parquet|orc|arrow}_skip_columns_with_unsupported_types_in_schema_inference`. These settings are disabled by default. - Allow to convert a column with type Null to a Nullable column with all NULL values in Arrow/Parquet formats. - Allow to specify column names in schema inference via setting `column_names_for_schema_inference` for formats that don't contain column names (like CSV, TSV, JSONCompactEachRow, etc) - Fix schema inference in ORC/Arrow/Parquet formats in terms of working with Nullable columns. Previously all inferred types were not Nullable and it blocked reading Nullable columns from data, now it's fixed and all inferred types are always Nullable (because we cannot understand that column is Nullable or not by reading the schema). - Fix schema inference in Template format with CSV escaping rules. [#35582](https://github.com/ClickHouse/ClickHouse/pull/35582) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* Add parallel parsing and schema inference for format `JSONAsObject`. [#35592](https://github.com/ClickHouse/ClickHouse/pull/35592) ([Anton Popov](https://github.com/CurtizJ)).
|
||||
* Added a support for automatic schema inference to `s3Cluster` table function. Synced the signatures of `s3 ` and `s3Cluster`. [#35544](https://github.com/ClickHouse/ClickHouse/pull/35544) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
|
||||
* Added support for schema inference for `hdfsCluster`. [#35602](https://github.com/ClickHouse/ClickHouse/pull/35602) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
|
||||
* Add new setting `input_format_json_read_bools_as_numbers` that allows to infer and parse bools as numbers in JSON input formats. It's enabled by default. Suggested by @alexey-milovidov. [#35735](https://github.com/ClickHouse/ClickHouse/pull/35735) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* Improve columns ordering in schema inference for formats TSKV and JSONEachRow, closes [#35640](https://github.com/ClickHouse/ClickHouse/issues/35640). Don't stop schema inference when reading empty row in schema inference for formats TSKV and JSONEachRow. [#35724](https://github.com/ClickHouse/ClickHouse/pull/35724) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* Add settings `input_format_orc_case_insensitive_column_matching`, `input_format_arrow_case_insensitive_column_matching`, and `input_format_parquet_case_insensitive_column_matching` which allows ClickHouse to use case insensitive matching of columns while reading data from ORC, Arrow or Parquet files. [#35459](https://github.com/ClickHouse/ClickHouse/pull/35459) ([Antonio Andelic](https://github.com/antonio2368)).
|
||||
* Added `is_secure` column to `system.query_log` which denotes if the client is using a secure connection over TCP or HTTP. [#35705](https://github.com/ClickHouse/ClickHouse/pull/35705) ([Antonio Andelic](https://github.com/antonio2368)).
|
||||
* Now `kafka_num_consumers` can be bigger than amount of physical cores in case of low resource machine (less than 16 cores). [#35926](https://github.com/ClickHouse/ClickHouse/pull/35926) ([alesapin](https://github.com/alesapin)).
|
||||
* Add some basic metrics to monitor engine=Kafka tables. [#35916](https://github.com/ClickHouse/ClickHouse/pull/35916) ([filimonov](https://github.com/filimonov)).
|
||||
* Now it's not allowed to `ALTER TABLE ... RESET SETTING` for non-existing settings for MergeTree engines family. Fixes [#35816](https://github.com/ClickHouse/ClickHouse/issues/35816). [#35884](https://github.com/ClickHouse/ClickHouse/pull/35884) ([alesapin](https://github.com/alesapin)).
