2024 Changelog

ClickHouse release v24.11.1.2557-stable (1574e794bf) FIXME as compared to v24.11.1.1-new (c82cf25b3e)

Backward Incompatible Change

  • Remove system tables generate_series and generateSeries. They were added by mistake here: #59390. #71091 (Alexey Milovidov).
  • Remove StorageExternalDistributed. Closes #70600. ### Documentation entry for user-facing changes. #71176 (flynn).
  • Fix possible error No such file or directory due to unescaped special symbols in files for JSON subcolumns. #71182 (Pavel Kruglov).
  • The table engines Kafka, NATS and RabbitMQ are now covered by their own grants in the SOURCES hierarchy. Add grants to any non-default database users that create tables with these engine types. #71250 (Christoph Wurm).
  • Check the full mutation query before executing it (including subqueries). This prevents accidentally running an invalid query and building up dead mutations that block valid mutations. #71300 (Christoph Wurm).
  • Rename filesystem cache setting skip_download_if_exceeds_query_cache to filesystem_cache_skip_download_if_exceeds_per_query_cache_write_limit. #71578 (Kseniia Sumarokova).
  • Remove support for Enum as well as UInt128 and UInt256 arguments in deltaSumTimestamp. Remove support for Int8, UInt8, Int16, and UInt16 of the second ("timestamp") argument of deltaSumTimestamp. #71790 (Alexey Milovidov).

New Feature

  • A new data type, BFloat16, represents 16-bit floating point numbers with 8-bit exponent, sign, and 7-bit mantissa. This closes #44206. This closes #49937. #64712 (Alexey Milovidov).
  • Added an option to select the side of the join that will act as the inner table in the query plan. This is controlled by query_plan_join_inner_table_selection, which can be set to auto. In this mode, ClickHouse will try to choose the table with the smallest number of rows. Resubmitted https://github.com/ClickHouse/ClickHouse/pull/71577. #68682 (Vladimir Cherkasov).
  • Add CHECK GRANT query to check whether the current user/role has been granted the specific privilege and whether the corresponding table/column exists in the memory. #68885 (Unalian).
  • Added SQL syntax to describe workload and resource management. https://clickhouse.com/docs/en/operations/workload-scheduling. #69187 (Sergei Trifonov).
  • Added server setting async_load_system_database that allows the server to start with not fully loaded system database. This helps to start ClickHouse faster if there are many system tables. #69847 (Sergei Trifonov).
  • Allow each authentication method to have its own expiration date, remove from user entity. #70090 (Arthur Passos).
  • Push external user roles from query originator to other nodes in cluster. Helpful when only originator has access to the external authenticator (like LDAP). #70332 (Andrey Zvonov).
  • Support alter from String to JSON. This PR also changes the serialization of JSON and Dynamic types to new version V2. Old version V1 can be still used by enabling setting merge_tree_use_v1_object_and_dynamic_serialization (can be used during upgrade to be able to rollback the version without issues). #70442 (Pavel Kruglov).
  • Added a new header type for S3 endpoints for user authentication (access_header). This allows to get some access header with the lowest priority, which will be overwritten with access_key_id from any other source (for example, a table schema or a named collection). #71011 (MikhailBurdukov).
  • Initial implementation of settings tiers. #71145 (Raúl Marín).
  • Add support for staleness clause in order by with fill operator. #71151 (Mikhail Artemenko).
  • Implement simple CAST from Map/Tuple/Object to new JSON through serialization/deserialization from JSON string. #71320 (Pavel Kruglov).
  • Added aliases anyRespectNulls, firstValueRespectNulls, and anyValueRespectNulls for aggregation function any. Also added aliases anyLastRespectNulls and lastValueRespectNulls for aggregation function anyLast. This allows using more natural camel-case-only syntax rather than mixed camel-case/underscore syntax, for example: SELECT anyLastRespectNullsStateIf instead of anyLast_respect_nullsStateIf. #71403 (Peter Nguyen).
  • Added the configuration date_time_utc parameter, enabling JSON log formatting to support UTC date-time in RFC 3339/ISO8601 format. #71560 (Ali).
  • Optimized memory usage for values of index granularity if granularity is constant for part. Added an ability to always select constant granularity for part (setting use_const_adaptive_granularity), which helps to ensure that it is always optimized in memory. It helps in large workloads (trillions of rows in shared storage) to avoid constantly growing memory usage by metadata (values of index granularity) of data parts. #71786 (Anton Popov).
  • Implement allowed_feature_tier as a global switch to disable all experimental / beta features. #71841 (Raúl Marín).
  • Add iceberg[S3;HDFS;Azure]Cluster, deltaLakeCluster, hudiCluster table functions. #72045 (Mikhail Artemenko).

Performance Improvement

  • Add 2 new settings short_circuit_function_evaluation_for_nulls and short_circuit_function_evaluation_for_nulls_threshold that allow to execute functions over Nullable columns in short-circuit manner when the ratio of NULL values in the block of data exceeds the specified threshold. It means that the function will be executed only on rows with non-null values. It applies only to functions that return NULL value for rows where at least one argument is NULL. #60129 (李扬).
  • Now we won't copy input blocks columns for join_algorithm='parallel_hash' when distribute them between threads for parallel processing. #67782 (Nikita Taranov).
  • Optimized Replacing merge algorithm for non intersecting parts. #70977 (Anton Popov).
  • Do not list detached parts from readonly and write-once disks for metrics and system.detached_parts. #71086 (Alexey Milovidov).
  • Do not calculate heavy asynchronous metrics by default. The feature was introduced in #40332, but it isn't good to have a heavy background job that is needed for only a single customer. #71087 (Alexey Milovidov).
  • Improve the performance and accuracy of system.query_metric_log collection interval by reducing the critical region. #71473 (Pablo Marcos).

Improvement

  • Higher-order functions with constant arrays and constant captured arguments will return constants. #58400 (Alexey Milovidov).
  • Read-in-order optimization via generating virtual rows, so less data would be read during merge sort especially useful when multiple parts exist. #62125 (Shichao Jin).
  • Query plan step names (EXPLAIN PLAN json=1) and pipeline processor names (EXPLAIN PIPELINE compact=0,graph=1) now have a unique id as a suffix. This allows to match processors profiler output and OpenTelemetry traces with explain output. #63518 (qhsong).
  • Added option to check object exists after writing to Azure Blob Storage, this is controlled by setting check_objects_after_upload. #64847 (Smita Kulkarni).
  • Fix use-after-dtor logic in HashTable destroyElements. #65279 (cangyin).
  • Use Atomic database by default in clickhouse-local. Address items 1 and 5 from #50647. Closes #44817. #68024 (Alexey Milovidov).
  • Write buffer has to be canceled or finalized explicitly. Exceptions break the HTTP protocol in order to alert the client about error. #68800 (Sema Checherinda).
  • Report running DDLWorker hosts by creating replica_dir and mark replicas active in DDLWorker. #69658 (tuanpach).
    1. Refactor DDLQueryStatusSource: * Rename DDLQueryStatusSource to DistributedQueryStatusSource, and make it a base class * Create two subclasses DDLOnClusterQueryStatusSource and ReplicatedDatabaseQueryStatusSource derived from DDLQueryStatusSource to query the status of DDL tasks from DDL On Cluster and Replicated databases respectively. 2. Support stop waiting for offline hosts in DDLOnClusterQueryStatusSource`. #69660 (tuanpach).
  • Don't allow Variant/Dynamic types in ORDER BY/GROUP BY/PARTITION BY/PRIMARY KEY by default because it may lead to unexpected results. #69731 (Pavel Kruglov).
  • Better error-handling and cancellation of ON CLUSTER backups and restores: - If a backup or restore fails on one host then it'll be cancelled on other hosts automatically - No weird errors must be produced because some hosts failed while other hosts continued their work - If a backup or restore is cancelled on one host then it'll be cancelled on other hosts automatically - Fix issues with test_disallow_concurrency - now disabling of concurrency must work better - Backups and restores now are much more resistant to ZooKeeper disconnects. #70027 (Vitaly Baranov).
  • Enable parallel_replicas_local_plan by default. Building a full-fledged local plan on the query initiator improves parallel replicas performance with less resource consumption, provides opportunities to apply more query optimizations. #70171 (Igor Nikonov).
  • Fix the metadata_version record in ZooKeeper in restarting thread rather than in attach thread. #70297 (Miсhael Stetsyuk).
  • Add ability to set user/password in http_handlers (for dynamic_query_handler/predefined_query_handler). #70725 (Azat Khuzhin).
  • Support ALTER TABLE ... MODIFY/RESET SETTING ... for certain settings in storage S3Queue. #70811 (Kseniia Sumarokova).
  • Do not call the object storage API when listing directories, as this may be cost-inefficient. Instead, store the list of filenames in the memory. The trade-offs are increased initial load time and memory required to store filenames. #70823 (Julia Kartseva).
  • Add --threads parameter to clickhouse-compressor, which allows to compress data in parallel. #70860 (Alexey Milovidov).
  • Fix the issue where ClickHouse in Docker containers printed "get_mempolicy: Operation not permitted" into stderr due to restricted syscalls. #70900 (filimonov).
  • Added the ability to reload client certificates in the same way as the procedure for reloading server certificates. #70997 (Roman Antonov).
  • Refactored internal structure of files which work with DataLake Storages. #71012 (Daniil Ivanik).
  • Make the Replxx client history size configurable. #71014 (Jiří Kozlovský).
  • Added a setting prewarm_mark_cache which enables loading of marks to mark cache on inserts, merges, fetches of parts and on startup of the table. #71053 (Anton Popov).
  • Boolean support for parquet native reader. #71055 (Arthur Passos).
  • Retry more errors when interacting with S3, such as "Malformed message". #71088 (Alexey Milovidov).
  • Lower log level for some messages about S3. #71090 (Alexey Milovidov).
  • Support write hdfs files with space. #71105 (exmy).
  • system.session_log is quite okay. This closes #51760. #71150 (Alexey Milovidov).
  • Fixes RIGHT / FULL joins in queries with parallel replicas. Now, RIGHT joins can be executed with parallel replicas (right table reading is distributed). FULL joins can't be parallelized among nodes, - executed locally. #71162 (Igor Nikonov).
  • Added settings limiting the number of replicated tables, dictionaries and views. #71179 (Kirill).
  • Use AWS_CONTAINER_AUTHORIZATION_TOKEN_FILE instead of AWS_CONTAINER_AUTHORIZATION_TOKEN if former is available. Fixes #71074. #71269 (Konstantin Bogdanov).
  • Remove the metadata_version ZooKeeper node creation from RMT restarting thread. The only scenario where we need to create this node is when the user updated from a version earlier than 20.4 straight to one later than 24.10. ClickHouse does not support upgrades that span more than a year, so we should throw an exception and ask the user to update gradually, instead of creating the node. #71385 (Miсhael Stetsyuk).
  • Add per host dashboards Overview (host) and Cloud overview (host) to advanced dashboard. #71422 (alesapin).
  • The methods removeObject and removeObjects are not idempotent. When retries happen due to network errors, the result could be object not found because it has been deleted at previous attempts. #71529 (Sema Checherinda).
  • Added new functions parseDateTime64, parseDateTime64OrNull and parseDateTime64OrZero. Compared to the existing function parseDateTime (and variants), they return a value of type DateTime64 instead of DateTime. #71581 (kevinyhzou).
  • Allow using clickhouse with a file argument as --queries-file. #71589 (Raúl Marín).
  • Shrink to fit index_granularity array in memory to reduce memory footprint for MergeTree table engines family. #71595 (alesapin).
  • clickhouse-local uses implicit SELECT by default, which allows to use it as a calculator. Improve the syntax highlighting for the implicit SELECT mode. #71620 (Alexey Milovidov).
  • The command line applications will highlight syntax even for multi-statements. #71622 (Alexey Milovidov).
  • Command-line applications will return non-zero exit codes on errors. In previous versions, the disks application returned zero on errors, and other applications returned zero for errors 256 (PARTITION_ALREADY_EXISTS) and 512 (SET_NON_GRANTED_ROLE). #71623 (Alexey Milovidov).
  • When user/group is given as ID, the clickhouse su fails. This patch fixes it to accept UID:GID as well. ### Documentation entry for user-facing changes. #71626 (Mikhail f. Shiryaev).
  • The Vertical format (which is also activated when you end your query with \G) gets the features of Pretty formats, such as: - highlighting thousand groups in numbers; - printing a readable number tip. #71630 (Alexey Milovidov).
  • Allow to disable memory buffer increase for filesystem cache via setting filesystem_cache_prefer_bigger_buffer_size. #71640 (Kseniia Sumarokova).
  • Add a separate setting background_download_max_file_segment_size for background download max file segment size in filesystem cache. #71648 (Kseniia Sumarokova).
  • Forbid Dynamic/Variant types in min/max functions to avoid confusion. #71761 (Pavel Kruglov).
  • Changes the default value of enable_http_compression from 0 to 1. Closes #71591. #71774 (Peter Nguyen).
  • Slightly better JSON type parsing: if current block for the JSON path contains values of several types, try to choose the best type by trying types in special best-effort order. #71785 (Pavel Kruglov).
  • Previously reading from system.asynchronous_metrics would wait for concurrent update to finish. This can take long time if system is under heavy load. With this change the previously collected values can always be read. #71798 (Alexander Gololobov).
  • Set polling_max_timeout_ms to 10 minutes, polling_backoff_ms to 30 seconds. #71817 (Kseniia Sumarokova).
  • Turn-off filesystem cache setting boundary_alignment for non-disk read. #71827 (Kseniia Sumarokova).
  • Update HostResolver 3 times in a history period. #71863 (Sema Checherinda).
  • Queries like 'SELECT * FROM t LIMIT 1' used to load part indexes even though they were not used. #71866 (Alexander Gololobov).
  • Allow_reorder_prewhere_conditions is on by default with old compatibility settings. #71867 (Raúl Marín).
  • Do not increment the ILLEGAL_TYPE_OF_ARGUMENT counter in the system.errors table when the bitmapTransform function is used, and argument types are valid. #71971 (Dmitry Novik).
  • When retrieving data directly from a dictionary using Dictionary storage, dictionary table function, or direct SELECT from the dictionary itself, it is now enough to have SELECT permission or dictGet permission for the dictionary. This aligns with previous attempts to prevent ACL bypasses: https://github.com/ClickHouse/ClickHouse/pull/57362 and https://github.com/ClickHouse/ClickHouse/pull/65359. It also makes the latter one backward compatible. #72051 (Nikita Mikhaylov).
  • On the advanced dashboard HTML page added a dropdown selector for the dashboard from system.dashboards table. #72081 (Sergei Trifonov).
  • Backported in #72471: Move JSON/Dynamic/Variant types from experimental features to beta. #72294 (Pavel Kruglov).

Bug Fix (user-visible misbehavior in an official stable release)

  • The parts deduplicated during ATTACH PART query don't get stuck with the attaching_ prefix anymore. #65636 (Kirill).
  • Fix for the bug when dateTime64 losing precision for the IN function. #67230 (Yarik Briukhovetskyi).
  • Fix possible logical error when using functions with IGNORE/RESPECT NULLS in ORDER BY ... WITH FILL, close #57609. #68234 (Vladimir Cherkasov).
  • Fixed rare logical errors in asynchronous inserts with format Native in case of reached memory limit. #68965 (Anton Popov).
  • Fix COMMENT in CREATE TABLE for EPHEMERAL column. #70458 (Yakov Olkhovskiy).
  • Fix logical error in JSONExtract with LowCardinality(Nullable). #70549 (Pavel Kruglov).
  • Allow system drop replica zkpath when there is another replica with the same zk path. #70642 (MikhailBurdukov).
  • GroupArraySortedData uses a PODArray with non-POD elements, manually calling constructors and destructors for the elements as needed. But it wasn't careful enough: in two places it forgot to call destructor, in one place it left elements uninitialized if an exception is thrown when deserializing previous elements. Then GroupArraySortedData's destructor called destructors on uninitialized elements and crashed: 2024.10.17 22:58:23.523790 [ 5233 ] {} <Fatal> BaseDaemon: ########## Short fault info ############ 2024.10.17 22:58:23.523834 [ 5233 ] {} <Fatal> BaseDaemon: (version 24.6.1.4609 (official build), build id: 5423339A6571004018D55BBE05D464AFA35E6718, git hash: fa6cdfda8a94890eb19bc7f22f8b0b56292f7a26) (from thread 682) Received signal 11 2024.10.17 22:58:23.523862 [ 5233 ] {} <Fatal> BaseDaemon: Signal description: Segmentation fault 2024.10.17 22:58:23.523883 [ 5233 ] {} <Fatal> BaseDaemon: Address: 0x8f.
