+### ClickHouse release v23.6.1.1524-stable (d1c7e13d088) FIXME as compared to v23.5.1.3174-stable (2fec796e73e)
+
+#### Backward Incompatible Change
+* Delete feature `do_not_evict_index_and_mark_files` in the fs cache. This feature was only making things worse. [#51253](https://github.com/ClickHouse/ClickHouse/pull/51253) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Remove ALTER support for experimental LIVE VIEW. [#51287](https://github.com/ClickHouse/ClickHouse/pull/51287) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+
+#### New Feature
+* Add setting `session_timezone`, it is used as default timezone for session when not explicitly specified. [#44149](https://github.com/ClickHouse/ClickHouse/pull/44149) ([Andrey Zvonov](https://github.com/zvonand)).
+* Added overlay database engine and representation of a directory as a database This commit adds 4 databases: 1. DatabaseOverlay: Implements the IDatabase interface. Allow to combine multiple databases, such as FileSystem and Memory. Internally, it stores a vector with other database pointers and proxies requests to them in turn until it is executed successfully. 2. DatabaseFilesystem: allows to read-only interact with files stored on the file system. Internally, it uses TableFunctionFile to implicitly load file when a user requests the table. Result of TableFunctionFile call cached inside to provide quick access. 3. DatabaseS3: allows to read-only interact with s3 storage. It uses TableFunctionS3 to implicitly load table from s3 4. DatabaseHDFS: allows to interact with hdfs storage. It uses TableFunctionHDFS to implicitly load table from hdfs. [#48821](https://github.com/ClickHouse/ClickHouse/pull/48821) ([alekseygolub](https://github.com/alekseygolub)).
+* Add a new setting named `use_mysql_types_in_show_columns` to alter the `SHOW COLUMNS` SQL statement to display MySQL equivalent types when a client is connected via the MySQL compatibility port. [#49577](https://github.com/ClickHouse/ClickHouse/pull/49577) ([Thomas Panetti](https://github.com/tpanetti)).
+* Added option `--rename_files_after_processing <pattern>`. This closes [#34207](https://github.com/ClickHouse/ClickHouse/issues/34207). [#49626](https://github.com/ClickHouse/ClickHouse/pull/49626) ([alekseygolub](https://github.com/alekseygolub)).
+* 1. Add `TableFunctionRedis` 3. Add table engine Redis 4. Add `RedisCommon` which contains Redis related tools and types 5. Support `equals` and `in` filter push down into Redis. [#50150](https://github.com/ClickHouse/ClickHouse/pull/50150) ([JackyWoo](https://github.com/JackyWoo)).
+* Allow to skip empty files in file/s3/url/hdfs table functions using settings `s3_skip_empty_files`, `hdfs_skip_empty_files`, `engine_file_skip_empty_files`, `engine_url_skip_empty_files`. [#50364](https://github.com/ClickHouse/ClickHouse/pull/50364) ([Kruglov Pavel](https://github.com/Avogar)).
+* Clickhouse-client can now be called with a connection instead of "--host", "--port", "--user" etc. [#50689](https://github.com/ClickHouse/ClickHouse/pull/50689) ([Alexey Gerasimchuck](https://github.com/Demilivor)).
+* Codec DEFLATE_QPL is now controlled via server setting "enable_deflate_qpl_codec" (default: false) instead of setting "allow_experimental_codecs". This marks QPL_DEFLATE non-experimental. [#50775](https://github.com/ClickHouse/ClickHouse/pull/50775) ([Robert Schulze](https://github.com/rschu1ze)).
+
+#### Performance Improvement
+* Improve performance with enabled QueryProfiler using thread-local timer_id instead of global object. [#48778](https://github.com/ClickHouse/ClickHouse/pull/48778) ([Jiebin Sun](https://github.com/jiebinn)).
+* Rewrite CapnProto input/output format to improve its performance. Map column names and CapnProto fields case insensitive, fix reading/writing of nested structure fields. [#49752](https://github.com/ClickHouse/ClickHouse/pull/49752) ([Kruglov Pavel](https://github.com/Avogar)).
+* Optimize parquet write performance for parallel threads. [#50102](https://github.com/ClickHouse/ClickHouse/pull/50102) ([Hongbin Ma](https://github.com/binmahone)).
+* ### Documentation entry for user-facing changes Disable `parallelize_output_from_storages` for processing MATERIALIZED VIEWs and storages with one block only. [#50214](https://github.com/ClickHouse/ClickHouse/pull/50214) ([Azat Khuzhin](https://github.com/azat)).
+* Merge PR https://github.com/ClickHouse/ClickHouse/pull/46558 (Avoid processing already sorted data). Avoid block permutation during sort if the block is already sorted. [#50697](https://github.com/ClickHouse/ClickHouse/pull/50697) ([Maksim Kita](https://github.com/kitaisreal)).
+* In the earlier PRs ([#50062](https://github.com/ClickHouse/ClickHouse/issues/50062), [#50307](https://github.com/ClickHouse/ClickHouse/issues/50307)), we used to propose an optimization pattern which transforms the predicates with toYear/toYYYYMM into its equivalent but converter-free form. This transformation could bring significant performance impact to some workloads, such as SSB. However, as issue [#50628](https://github.com/ClickHouse/ClickHouse/issues/50628) indicated, these two PRs would introduce some issues which may results in incomplete query results, and as a result, they were reverted by [#50629](https://github.com/ClickHouse/ClickHouse/issues/50629). [#50951](https://github.com/ClickHouse/ClickHouse/pull/50951) ([Zhiguo Zhou](https://github.com/ZhiguoZh)).
+* Make multiple list requests to ZooKeeper in parallel to speed up reading from system.zookeeper table. [#51042](https://github.com/ClickHouse/ClickHouse/pull/51042) ([Alexander Gololobov](https://github.com/davenger)).
+* Speedup initialization of DateTime lookup tables for time zones. This should reduce startup/connect time of clickhouse client especially in debug build as it is rather heavy. [#51347](https://github.com/ClickHouse/ClickHouse/pull/51347) ([Alexander Gololobov](https://github.com/davenger)).
+
+#### Improvement
+* Allow to cast IPv6 to IPv4 address for CIDR ::ffff:0:0/96 (IPv4-mapped addresses). [#49759](https://github.com/ClickHouse/ClickHouse/pull/49759) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
+* Update MongoDB protocol to support MongoDB 5.1 version and newer. Support for the versions with the old protocol (<3.6) is preserved. Closes [#45621](https://github.com/ClickHouse/ClickHouse/issues/45621), [#49879](https://github.com/ClickHouse/ClickHouse/issues/49879). [#50061](https://github.com/ClickHouse/ClickHouse/pull/50061) ([Nikolay Degterinsky](https://github.com/evillique)).
+* Improved scheduling of merge selecting and cleanup tasks in `ReplicatedMergeTree`. The tasks will not be executed too frequently when there's nothing to merge or cleanup. Added settings `max_merge_selecting_sleep_ms`, `merge_selecting_sleep_slowdown_factor`, `max_cleanup_delay_period` and `cleanup_thread_preferred_points_per_iteration`. It should close [#31919](https://github.com/ClickHouse/ClickHouse/issues/31919). [#50107](https://github.com/ClickHouse/ClickHouse/pull/50107) ([Alexander Tokmakov](https://github.com/tavplubix)).
+* Support parallel replicas with the analyzer. [#50441](https://github.com/ClickHouse/ClickHouse/pull/50441) ([Raúl Marín](https://github.com/Algunenano)).
+* Add setting `input_format_max_bytes_to_read_for_schema_inference` to limit the number of bytes to read in schema inference. Closes [#50577](https://github.com/ClickHouse/ClickHouse/issues/50577). [#50592](https://github.com/ClickHouse/ClickHouse/pull/50592) ([Kruglov Pavel](https://github.com/Avogar)).
+* Respect setting input_format_as_default in schema inference. [#50602](https://github.com/ClickHouse/ClickHouse/pull/50602) ([Kruglov Pavel](https://github.com/Avogar)).
+* Make filter push down through cross join. [#50605](https://github.com/ClickHouse/ClickHouse/pull/50605) ([Han Fei](https://github.com/hanfei1991)).
+* Actual lz4 version is used now. [#50621](https://github.com/ClickHouse/ClickHouse/pull/50621) ([Nikita Taranov](https://github.com/nickitat)).
+* Allow to skip trailing empty lines in CSV/TSV/CustomSeparated formats via settings `input_format_csv_skip_trailing_empty_lines`, `input_format_tsv_skip_trailing_empty_lines` and `input_format_custom_skip_trailing_empty_lines` (disabled by default). Closes [#49315](https://github.com/ClickHouse/ClickHouse/issues/49315). [#50635](https://github.com/ClickHouse/ClickHouse/pull/50635) ([Kruglov Pavel](https://github.com/Avogar)).
+* Functions "toDateOrDefault|OrNull()" and "accuateCast[OrDefault|OrNull]()" now correctly parse numeric arguments. [#50709](https://github.com/ClickHouse/ClickHouse/pull/50709) ([Dmitry Kardymon](https://github.com/kardymonds)).
+* Currently, the csv input format can not parse the csv file with whitespace or \t field delimiter, and these delimiters is supported in spark. [#50712](https://github.com/ClickHouse/ClickHouse/pull/50712) ([KevinyhZou](https://github.com/KevinyhZou)).
+* Settings `number_of_mutations_to_delay` and `number_of_mutations_to_throw` are enabled by default now with values 500 and 1000 respectively. [#50726](https://github.com/ClickHouse/ClickHouse/pull/50726) ([Anton Popov](https://github.com/CurtizJ)).
+* Keeper improvement: add feature flags for Keeper API. Each feature flag can be disabled or enabled by defining it under `keeper_server.feature_flags` config. E.g. to enable `CheckNotExists` request, `keeper_server.feature_flags.check_not_exists` should be set to `1` on Keeper. [#50796](https://github.com/ClickHouse/ClickHouse/pull/50796) ([Antonio Andelic](https://github.com/antonio2368)).
+* The dashboard correctly shows missing values. This closes [#50831](https://github.com/ClickHouse/ClickHouse/issues/50831). [#50832](https://github.com/ClickHouse/ClickHouse/pull/50832) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* CGroups metrics related to CPU are replaced with one metric, `CGroupMaxCPU` for better usability. The `Normalized` CPU usage metrics will be normalized to CGroups limits instead of the total number of CPUs when they are set. This closes [#50836](https://github.com/ClickHouse/ClickHouse/issues/50836). [#50835](https://github.com/ClickHouse/ClickHouse/pull/50835) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Relax the thresholds for "too many parts" to be more modern. Return the backpressure during long-running insert queries. [#50856](https://github.com/ClickHouse/ClickHouse/pull/50856) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Added the possibility to use date and time arguments in syslog timestamp format in functions parseDateTimeBestEffort*() and parseDateTime64BestEffort*(). [#50925](https://github.com/ClickHouse/ClickHouse/pull/50925) ([Victor Krasnov](https://github.com/sirvickr)).
+* Suggest using `APPEND` or `TRUNCATE` for `INTO OUTFILE` when file exists. [#50950](https://github.com/ClickHouse/ClickHouse/pull/50950) ([alekar](https://github.com/alekar)).
+* Add embedded keeper-client to standalone keeper binary. [#50964](https://github.com/ClickHouse/ClickHouse/pull/50964) ([pufit](https://github.com/pufit)).
+* Command line parameter "--password" in clickhouse-client can now be specified only once. [#50966](https://github.com/ClickHouse/ClickHouse/pull/50966) ([Alexey Gerasimchuck](https://github.com/Demilivor)).
+* Fix data lakes slowness because of synchronous head requests. (Related to Iceberg/Deltalake/Hudi being slow with a lot of files). [#50976](https://github.com/ClickHouse/ClickHouse/pull/50976) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Use `hash_of_all_files` from `system.parts` to check identity of parts during on-cluster backups. [#50997](https://github.com/ClickHouse/ClickHouse/pull/50997) ([Vitaly Baranov](https://github.com/vitlibar)).
+* The system table zookeeper_connection connected_time identifies the time when the connection is established (standard format), and session_uptime_elapsed_seconds is added, which labels the duration of the established connection session (in seconds). [#51026](https://github.com/ClickHouse/ClickHouse/pull/51026) ([郭小龙](https://github.com/guoxiaolongzte)).
+* Show halves of checksums in `system.parts`, `system.projection_parts` and in error messages in the correct order. [#51040](https://github.com/ClickHouse/ClickHouse/pull/51040) ([Vitaly Baranov](https://github.com/vitlibar)).
+* Do not replicate `ALTER PARTITION` queries and mutations through `Replicated` database if it has only one shard and the underlying table is `ReplicatedMergeTree`. [#51049](https://github.com/ClickHouse/ClickHouse/pull/51049) ([Alexander Tokmakov](https://github.com/tavplubix)).
+* Improve the progress bar for file/s3/hdfs/url table functions by using chunk size from source data and using incremental total size counting in each thread. Fix the progress bar for *Cluster functions. This closes [#47250](https://github.com/ClickHouse/ClickHouse/issues/47250). [#51088](https://github.com/ClickHouse/ClickHouse/pull/51088) ([Kruglov Pavel](https://github.com/Avogar)).
+* Add total_bytes_to_read to Progress packet in TCP protocol for better Progress bar. [#51158](https://github.com/ClickHouse/ClickHouse/pull/51158) ([Kruglov Pavel](https://github.com/Avogar)).

+* Fix sometimes not correct current_elements_num in fs cache. [#51242](https://github.com/ClickHouse/ClickHouse/pull/51242) ([Kseniia Sumarokova](https://github.com/kssenii)).
+* Add random sleep before merges/mutations execution to split load more evenly between replicas in case of zero-copy replication. [#51282](https://github.com/ClickHouse/ClickHouse/pull/51282) ([alesapin](https://github.com/alesapin)).
+* The function `transform` as well as `CASE` with value matching started to support all data types. This closes [#29730](https://github.com/ClickHouse/ClickHouse/issues/29730). This closes [#32387](https://github.com/ClickHouse/ClickHouse/issues/32387). This closes [#50827](https://github.com/ClickHouse/ClickHouse/issues/50827). This closes [#31336](https://github.com/ClickHouse/ClickHouse/issues/31336). This closes [#40493](https://github.com/ClickHouse/ClickHouse/issues/40493).

+* We have found a bug in LLVM that makes the usage of `compile_expressions` setting unsafe. It is disabled by default. [#51368](https://github.com/ClickHouse/ClickHouse/pull/51368) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
+* Issue [#50220](https://github.com/ClickHouse/ClickHouse/issues/50220) reports a core in `grace_hash` join. We finally reproduce the exception on local, and found that the issue is related to the failure of creating temporary file. Somehow this is triggered in https://github.com/ClickHouse/ClickHouse/pull/49816 https://github.com/ClickHouse/ClickHouse/pull/49483. [#51382](https://github.com/ClickHouse/ClickHouse/pull/51382) ([lgbo](https://github.com/lgbo-ustc)).
+
+#### Build/Testing/Packaging Improvement
+* Update contrib/re2 to 2023-06-02. [#50949](https://github.com/ClickHouse/ClickHouse/pull/50949) ([Yuriy Chernyshov](https://github.com/georgthegreat)).

+* In https://github.com/ClickHouse/ClickHouse/pull/51143 the fasstests failed, but the status wasn't created because of the chown `file not found`. This addresses it. Decrease the default values for `http-max-field-value-size` and `http_max_field_name_size` to 128K. [#51163](https://github.com/ClickHouse/ClickHouse/pull/51163) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
+* Update Ubuntu version in docker containers. [#51180](https://github.com/ClickHouse/ClickHouse/pull/51180) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
+* Allow building ClickHouse with clang-17. [#51300](https://github.com/ClickHouse/ClickHouse/pull/51300) ([Alexey Milovidov](https://github.com/alexey-milovidov)).

 # Settings Overview
 
-There are multiple ways to define ClickHouse settings. Settings are configured in layers, and each subsequent layer redefines the previous values of a setting.
+There are two main groups of ClickHouse settings:
 
-The order of priority for defining a setting is:
+- Global server settings
+- Query-level settings
 
-1. Settings in the `users.xml` server configuration file
+The main distinction between global server settings and query-level settings is that
+global server settings must be set in configuration files while query-level settings
+can be set in configuration files or with SQL queries.
 
-    - Set in the element `<profiles>`.
+Read about [global server settings](/docs/en/operations/server-configuration-parameters/settings.md) to learn more about configuring your ClickHouse server at the global server level.
 
-2. Session settings
+Read about [query-level settings](/docs/en/operations/settings/settings-query-level.md) to learn more about configuring your ClickHouse server at the query-level.
 
-    - Send `SET setting=value` from the ClickHouse console client in interactive mode.
-    Similarly, you can use ClickHouse sessions in the HTTP protocol. To do this, you need to specify the `session_id` HTTP parameter.
-
-3. Query settings
-
-    - When starting the ClickHouse console client in non-interactive mode, set the startup parameter `--setting=value`.
-    - When using the HTTP API, pass CGI parameters (`URL?setting_1=value&setting_2=value...`).
-    - Define settings in the [SETTINGS](../../sql-reference/statements/select/index.md#settings-in-select-query) clause of the SELECT query. The setting value is applied only to that query and is reset to the default or previous value after the query is executed.
-
-View the [Settings](./settings.md) page for a description of the ClickHouse settings.
-
-## Converting a Setting to its Default Value
-
-If you change a setting and would like to revert it back to its default value, set the value to `DEFAULT`. The syntax looks like:
-
-```sql
-SET setting_name = DEFAULT
-```
-
-For example, the default value of `max_insert_block_size` is 1048449. Suppose you change its value to 100000:
-
-```sql
-SET max_insert_block_size=100000;
-
-SELECT value FROM system.settings where name='max_insert_block_size';
-```
-
-The response is:
-
-```response
-┌─value──┐
-│ 100000 │
-└────────┘
-```
-
-The following command sets its value back to 1048449:
-
-```sql
-SET max_insert_block_size=DEFAULT;
-
-SELECT value FROM system.settings where name='max_insert_block_size';
-```
-
-The setting is now back to its default:
-
-```response
-┌─value───┐
-│ 1048449 │
-└─────────┘
-```
-
-
-## Custom Settings {#custom_settings}
-
-In addition to the common [settings](../../operations/settings/settings.md), users can define custom settings.
-
-A custom setting name must begin with one of predefined prefixes. The list of these prefixes must be declared in the [custom_settings_prefixes](../../operations/server-configuration-parameters/settings.md#custom_settings_prefixes) parameter in the server configuration file.
-
-```xml

+title: Query-level Settings
+slug: /en/operations/settings/query-level
+---
+
+There are multiple ways to set ClickHouse query-level settings. Settings are configured in layers, and each subsequent layer redefines the previous values of a setting.
+
+The order of priority for defining a setting is:
+
+1. Applying a setting to a user directly, or within a settings profile
+
+    - SQL (recommended)
+    - adding one or more XML or YAML files to `/etc/clickhouse-server/users.d`
+
+2. Session settings
+
+    - Send `SET setting=value` from the ClickHouse Cloud SQL console or
+    `clickhouse client` in interactive mode. Similarly, you can use ClickHouse
+    sessions in the HTTP protocol. To do this, you need to specify the
+    `session_id` HTTP parameter.
+
+3. Query settings
+
+    - When starting `clickhouse client` in non-interactive mode, set the startup
+    parameter `--setting=value`.
+    - When using the HTTP API, pass CGI parameters (`URL?setting_1=value&setting_2=value...`).
+    - Define settings in the
+    [SETTINGS](../../sql-reference/statements/select/index.md#settings-in-select-query)
+    clause of the SELECT query. The setting value is applied only to that query
+    and is reset to the default or previous value after the query is executed.
+
+## Examples
+
+These examples all set the value of the `async_insert` setting to `1`, and
+show how to examine the settings in a running system.
+
+### Using SQL to apply a setting to a user directly
+
+This creates the user `ingester` with the setting `async_inset = 1`:
+
+```sql
+CREATE USER ingester
+IDENTIFIED WITH sha256_hash BY '7e099f39b84ea79559b3e85ea046804e63725fd1f46b37f281276aae20f86dc3'
+# highlight-next-line
+SETTINGS async_insert = 1
+```
+
+#### Examine the settings profile and assignment
+
+```sql

+└────────────────────────────────────────────────────────────────────────────────────┘
+```
+### Using SQL to create a settings profile and assign to a user
+
+This creates the profile `log_ingest` with the setting `async_inset = 1`:
+
+```sql
+CREATE
+SETTINGS PROFILE log_ingest SETTINGS async_insert = 1
+```
+
+This creates the user `ingester` and assigns the user the settings profile `log_ingest`:
+
+```sql
+CREATE USER ingester
+IDENTIFIED WITH sha256_hash BY '7e099f39b84ea79559b3e85ea046804e63725fd1f46b37f281276aae20f86dc3'

+
+
+## Converting a Setting to its Default Value
+
+If you change a setting and would like to revert it back to its default value, set the value to `DEFAULT`. The syntax looks like:
+
+```sql
+SET setting_name = DEFAULT
+```
+
+For example, the default value of `async_insert` is `0`. Suppose you change its value to `1`:
+
+```sql
+SET async_insert = 1;
+
+SELECT value FROM system.settings where name='async_insert';
+```
+
+The response is:
+
+```response
+┌─value──┐
+│ 1      │
+└────────┘
+```
+
+The following command sets its value back to 0:
+
+```sql
+SET async_insert = DEFAULT;
+
+SELECT value FROM system.settings where name='async_insert';
+```
+
+The setting is now back to its default:
+
+```response
+┌─value───┐
+│ 0       │
+└─────────┘
+```
+
+## Custom Settings {#custom_settings}
+
+In addition to the common [settings](../../operations/settings/settings.md), users can define custom settings.
+
+A custom setting name must begin with one of predefined prefixes. The list of these prefixes must be declared in the [custom_settings_prefixes](../../operations/server-configuration-parameters/settings.md#custom_settings_prefixes) parameter in the server configuration file.
+
+```xml
+<custom_settings_prefixes>custom_</custom_settings_prefixes>
+```
+
+To define a custom setting use `SET` command:
+
+```sql
+SET custom_a = 123;
+```
+
+To get the current value of a custom setting use `getSetting()` function:
+
+```sql
+SELECT getSetting('custom_a');
+```
