## ClickHouse release 21.3
### ClickHouse release v21.3, 2021-03-12
#### Backward Incompatible Change
* Now it's not allowed to create MergeTree tables in old syntax with table TTL because it's just ignored. Attach of old tables is still possible. [#20282](https://github.com/ClickHouse/ClickHouse/pull/20282) ([alesapin](https://github.com/alesapin)).
* Now all case-insensitive function names will be rewritten to their canonical representations. This is needed for projection query routing (the upcoming feature). [#20174](https://github.com/ClickHouse/ClickHouse/pull/20174) ([Amos Bird](https://github.com/amosbird)).
* Fix creation of `TTL` in cases, when its expression is a function and it is the same as `ORDER BY` key. Now it's allowed to set custom aggregation to primary key columns in `TTL` with `GROUP BY`. Backward incompatible: For primary key columns, which are not in `GROUP BY` and aren't set explicitly now is applied function `any` instead of `max`, when TTL is expired. Also if you use TTL with `WHERE` or `GROUP BY` you can see exceptions at merges, while making rolling update. [#15450](https://github.com/ClickHouse/ClickHouse/pull/15450) ([Anton Popov](https://github.com/CurtizJ)).
#### New Feature
* Add file engine settings: `engine_file_empty_if_not_exists` and `engine_file_truncate_on_insert`. [#20620](https://github.com/ClickHouse/ClickHouse/pull/20620) ([M0r64n](https://github.com/M0r64n)).
* Add aggregate function `deltaSum` for summing the differences between consecutive rows. [#20057](https://github.com/ClickHouse/ClickHouse/pull/20057) ([Russ Frank](https://github.com/rf)).
* New `event_time_microseconds` column in `system.part_log` table. [#20027](https://github.com/ClickHouse/ClickHouse/pull/20027) ([Bharat Nallan](https://github.com/bharatnc)).
* Added `timezoneOffset(datetime)` function which will give the offset from UTC in seconds. This close [#issue:19850](https://github.com/ClickHouse/ClickHouse/issues/19850). [#19962](https://github.com/ClickHouse/ClickHouse/pull/19962) ([keenwolf](https://github.com/keen-wolf)).
* Add setting `insert_shard_id` to support insert data into specific shard from distributed table. [#19961](https://github.com/ClickHouse/ClickHouse/pull/19961) ([flynn](https://github.com/ucasFL)).
* Function `reinterpretAs` updated to support big integers. Fixes [#19691](https://github.com/ClickHouse/ClickHouse/issues/19691). [#19858](https://github.com/ClickHouse/ClickHouse/pull/19858) ([Maksim Kita](https://github.com/kitaisreal)).
* Added Server Side Encryption Customer Keys (the `x-amz-server-side-encryption-customer-(key/md5)` header) support in S3 client. See [the link](https://docs.aws.amazon.com/AmazonS3/latest/dev/ServerSideEncryptionCustomerKeys.html). Closes [#19428](https://github.com/ClickHouse/ClickHouse/issues/19428). [#19748](https://github.com/ClickHouse/ClickHouse/pull/19748) ([Vladimir Chebotarev](https://github.com/excitoon)).
* Added `implicit_key` option for `executable` dictionary source. It allows to avoid printing key for every record if records comes in the same order as the input keys. Implements [#14527](https://github.com/ClickHouse/ClickHouse/issues/14527). [#19677](https://github.com/ClickHouse/ClickHouse/pull/19677) ([Maksim Kita](https://github.com/kitaisreal)).
* Add quota type `query_selects` and `query_inserts`. [#19603](https://github.com/ClickHouse/ClickHouse/pull/19603) ([JackyWoo](https://github.com/JackyWoo)).
* Add function `extractTextFromHTML` [#19600](https://github.com/ClickHouse/ClickHouse/pull/19600) ([zlx19950903](https://github.com/zlx19950903)), ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Tables with `MergeTree*` engine now have two new table-level settings for query concurrency control. Setting `max_concurrent_queries` limits the number of concurrently executed queries which are related to this table. Setting `min_marks_to_honor_max_concurrent_queries` tells to apply previous setting only if query reads at least this number of marks. [#19544](https://github.com/ClickHouse/ClickHouse/pull/19544) ([Amos Bird](https://github.com/amosbird)).
* Added `file` function to read file from user_files directory as a String. This is different from the `file` table function. This implements [#issue:18851](https://github.com/ClickHouse/ClickHouse/issues/18851). [#19204](https://github.com/ClickHouse/ClickHouse/pull/19204) ([keenwolf](https://github.com/keen-wolf)).
#### Experimental feature
* Add experimental `Replicated` database engine. It replicates DDL queries across multiple hosts. [#16193](https://github.com/ClickHouse/ClickHouse/pull/16193) ([tavplubix](https://github.com/tavplubix)).
* Introduce experimental support for window functions, enabled with `allow_experimental_functions = 1`. This is a preliminary, alpha-quality implementation that is not suitable for production use and will change in backward-incompatible ways in future releases. Please see [the documentation](https://github.com/ClickHouse/ClickHouse/blob/master/docs/en/sql-reference/window-functions/index.md#experimental-window-functions) for the list of supported features. [#20337](https://github.com/ClickHouse/ClickHouse/pull/20337) ([Alexander Kuzmenkov](https://github.com/akuzm)).
* Add the ability to backup/restore metadata files for DiskS3. [#18377](https://github.com/ClickHouse/ClickHouse/pull/18377) ([Pavel Kovalenko](https://github.com/Jokser)).
#### Performance Improvement
* Hedged requests for remote queries. When setting `use_hedged_requests` enabled (off by default), allow to establish many connections with different replicas for query. New connection is enabled in case existent connection(s) with replica(s) were not established within `hedged_connection_timeout` or no data was received within `receive_data_timeout`. Query uses the first connection which send non empty progress packet (or data packet, if `allow_changing_replica_until_first_data_packet`); other connections are cancelled. Queries with `max_parallel_replicas > 1` are supported. [#19291](https://github.com/ClickHouse/ClickHouse/pull/19291) ([Kruglov Pavel](https://github.com/Avogar)). This allows to significantly reduce tail latencies on very large clusters.
* Added support for `PREWHERE` (and enable the corresponding optimization) when tables have row-level security expressions specified. [#19576](https://github.com/ClickHouse/ClickHouse/pull/19576) ([Denis Glazachev](https://github.com/traceon)).
* The setting `distributed_aggregation_memory_efficient` is enabled by default. It will lower memory usage and improve performance of distributed queries. [#20599](https://github.com/ClickHouse/ClickHouse/pull/20599) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Improve performance of GROUP BY multiple fixed size keys. [#20472](https://github.com/ClickHouse/ClickHouse/pull/20472) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Improve performance of aggregate functions by more strict aliasing. [#19946](https://github.com/ClickHouse/ClickHouse/pull/19946) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Speed up reading from `Memory` tables in extreme cases (when reading speed is in order of 50 GB/sec) by simplification of pipeline and (consequently) less lock contention in pipeline scheduling. [#20468](https://github.com/ClickHouse/ClickHouse/pull/20468) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Partially reimplement HTTP server to make it making less copies of incoming and outgoing data. It gives up to 1.5 performance improvement on inserting long records over HTTP. [#19516](https://github.com/ClickHouse/ClickHouse/pull/19516) ([Ivan](https://github.com/abyss7)).
* Add `compress` setting for `Memory` tables. If it's enabled the table will use less RAM. On some machines and datasets it can also work faster on SELECT, but it is not always the case. This closes [#20093](https://github.com/ClickHouse/ClickHouse/issues/20093). Note: there are reasons why Memory tables can work slower than MergeTree: (1) lack of compression (2) static size of blocks (3) lack of indices and prewhere... [#20168](https://github.com/ClickHouse/ClickHouse/pull/20168) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Slightly better code in aggregation. [#20978](https://github.com/ClickHouse/ClickHouse/pull/20978) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Add back `intDiv`/`modulo` specializations for better performance. This fixes [#21293](https://github.com/ClickHouse/ClickHouse/issues/21293) . The regression was introduced in https://github.com/ClickHouse/ClickHouse/pull/18145 . [#21307](https://github.com/ClickHouse/ClickHouse/pull/21307) ([Amos Bird](https://github.com/amosbird)).
* Do not squash blocks too much on INSERT SELECT if inserting into Memory table. In previous versions inefficient data representation was created in Memory table after INSERT SELECT. This closes [#13052](https://github.com/ClickHouse/ClickHouse/issues/13052). [#20169](https://github.com/ClickHouse/ClickHouse/pull/20169) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Fix at least one case when DataType parser may have exponential complexity (found by fuzzer). This closes [#20096](https://github.com/ClickHouse/ClickHouse/issues/20096). [#20132](https://github.com/ClickHouse/ClickHouse/pull/20132) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Parallelize SELECT with FINAL for single part with level > 0 when `do_not_merge_across_partitions_select_final` setting is 1. [#19375](https://github.com/ClickHouse/ClickHouse/pull/19375) ([Kruglov Pavel](https://github.com/Avogar)).
* Fill only requested columns when querying `system.parts` and `system.parts_columns`. Closes [#19570](https://github.com/ClickHouse/ClickHouse/issues/19570). [#21035](https://github.com/ClickHouse/ClickHouse/pull/21035) ([Anmol Arora](https://github.com/anmolarora)).
* Perform algebraic optimizations of arithmetic expressions inside `avg` aggregate function. close [#20092](https://github.com/ClickHouse/ClickHouse/issues/20092). [#20183](https://github.com/ClickHouse/ClickHouse/pull/20183) ([flynn](https://github.com/ucasFL)).
#### Improvement
* Case-insensitive compression methods for table functions. Also fixed LZMA compression method which was checked in upper case. [#21416](https://github.com/ClickHouse/ClickHouse/pull/21416) ([Vladimir Chebotarev](https://github.com/excitoon)).
* Add two settings to delay or throw error during insertion when there are too many inactive parts. This is useful when server fails to clean up parts quickly enough. [#20178](https://github.com/ClickHouse/ClickHouse/pull/20178) ([Amos Bird](https://github.com/amosbird)).
* Provide better compatibility for mysql clients. 1. mysql jdbc 2. mycli. [#21367](https://github.com/ClickHouse/ClickHouse/pull/21367) ([Amos Bird](https://github.com/amosbird)).
* Forbid to drop a column if it's referenced by materialized view. Closes [#21164](https://github.com/ClickHouse/ClickHouse/issues/21164). [#21303](https://github.com/ClickHouse/ClickHouse/pull/21303) ([flynn](https://github.com/ucasFL)).
* MySQL dictionary source will now retry unexpected connection failures (Lost connection to MySQL server during query) which sometimes happen on SSL/TLS connections. [#21237](https://github.com/ClickHouse/ClickHouse/pull/21237) ([Alexander Kazakov](https://github.com/Akazz)).
* Usability improvement: more consistent `DateTime64` parsing: recognize the case when unix timestamp with subsecond resolution is specified as scaled integer (like `1111111111222` instead of `1111111111.222`). This closes [#13194](https://github.com/ClickHouse/ClickHouse/issues/13194). [#21053](https://github.com/ClickHouse/ClickHouse/pull/21053) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Do only merging of sorted blocks on initiator with distributed_group_by_no_merge. [#20882](https://github.com/ClickHouse/ClickHouse/pull/20882) ([Azat Khuzhin](https://github.com/azat)).
* When loading config for mysql source ClickHouse will now randomize the list of replicas with the same priority to ensure the round-robin logics of picking mysql endpoint. This closes [#20629](https://github.com/ClickHouse/ClickHouse/issues/20629). [#20632](https://github.com/ClickHouse/ClickHouse/pull/20632) ([Alexander Kazakov](https://github.com/Akazz)).
* Function 'reinterpretAs(x, Type)' renamed into 'reinterpret(x, Type)'. [#20611](https://github.com/ClickHouse/ClickHouse/pull/20611) ([Maksim Kita](https://github.com/kitaisreal)).
* Support vhost for RabbitMQ engine [#20576](https://github.com/ClickHouse/ClickHouse/issues/20576). [#20596](https://github.com/ClickHouse/ClickHouse/pull/20596) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Improved serialization for data types combined of Arrays and Tuples. Improved matching enum data types to protobuf enum type. Fixed serialization of the `Map` data type. Omitted values are now set by default. [#20506](https://github.com/ClickHouse/ClickHouse/pull/20506) ([Vitaly Baranov](https://github.com/vitlibar)).
* Fixed race between execution of distributed DDL tasks and cleanup of DDL queue. Now DDL task cannot be removed from ZooKeeper if there are active workers. Fixes [#20016](https://github.com/ClickHouse/ClickHouse/issues/20016). [#20448](https://github.com/ClickHouse/ClickHouse/pull/20448) ([tavplubix](https://github.com/tavplubix)).
* Make FQDN and other DNS related functions work correctly in alpine images. [#20336](https://github.com/ClickHouse/ClickHouse/pull/20336) ([filimonov](https://github.com/filimonov)).
* Do not allow early constant folding of explicitly forbidden functions. [#20303](https://github.com/ClickHouse/ClickHouse/pull/20303) ([Azat Khuzhin](https://github.com/azat)).
* Implicit conversion from integer to Decimal type might succeeded if integer value doe not fit into Decimal type. Now it throws `ARGUMENT_OUT_OF_BOUND`. [#20232](https://github.com/ClickHouse/ClickHouse/pull/20232) ([tavplubix](https://github.com/tavplubix)).
* Lockless `SYSTEM FLUSH DISTRIBUTED`. [#20215](https://github.com/ClickHouse/ClickHouse/pull/20215) ([Azat Khuzhin](https://github.com/azat)).
* Normalize count(constant), sum(1) to count(). This is needed for projection query routing. [#20175](https://github.com/ClickHouse/ClickHouse/pull/20175) ([Amos Bird](https://github.com/amosbird)).
* Support all native integer types in bitmap functions. [#20171](https://github.com/ClickHouse/ClickHouse/pull/20171) ([Amos Bird](https://github.com/amosbird)).
* Updated `CacheDictionary`, `ComplexCacheDictionary`, `SSDCacheDictionary`, `SSDComplexKeyDictionary` to use LRUHashMap as underlying index. [#20164](https://github.com/ClickHouse/ClickHouse/pull/20164) ([Maksim Kita](https://github.com/kitaisreal)).
* The setting `access_management` is now configurable on startup by providing `CLICKHOUSE_DEFAULT_ACCESS_MANAGEMENT`, defaults to disabled (`0`) which was the prior value. [#20139](https://github.com/ClickHouse/ClickHouse/pull/20139) ([Marquitos](https://github.com/sonirico)).
* Fix toDateTime64(toDate()/toDateTime()) for DateTime64 - Implement DateTime64 clamping to match DateTime behaviour. [#20131](https://github.com/ClickHouse/ClickHouse/pull/20131) ([Azat Khuzhin](https://github.com/azat)).
* Quota improvements: SHOW TABLES is now considered as one query in the quota calculations, not two queries. SYSTEM queries now consume quota. Fix calculation of interval's end in quota consumption. [#20106](https://github.com/ClickHouse/ClickHouse/pull/20106) ([Vitaly Baranov](https://github.com/vitlibar)).
* Supports `path IN (set)` expressions for `system.zookeeper` table. [#20105](https://github.com/ClickHouse/ClickHouse/pull/20105) ([小路](https://github.com/nicelulu)).
* Show full details of `MaterializeMySQL` tables in `system.tables`. [#20051](https://github.com/ClickHouse/ClickHouse/pull/20051) ([Stig Bakken](https://github.com/stigsb)).
* Fix data race in executable dictionary that was possible only on misuse (when the script returns data ignoring its input). [#20045](https://github.com/ClickHouse/ClickHouse/pull/20045) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* The value of MYSQL_OPT_RECONNECT option can now be controlled by "opt_reconnect" parameter in the config section of mysql replica. [#19998](https://github.com/ClickHouse/ClickHouse/pull/19998) ([Alexander Kazakov](https://github.com/Akazz)).
* If user calls `JSONExtract` function with `Float32` type requested, allow inaccurate conversion to the result type. For example the number `0.1` in JSON is double precision and is not representable in Float32, but the user still wants to get it. Previous versions return 0 for non-Nullable type and NULL for Nullable type to indicate that conversion is imprecise. The logic was 100% correct but it was surprising to users and leading to questions. This closes [#13962](https://github.com/ClickHouse/ClickHouse/issues/13962). [#19960](https://github.com/ClickHouse/ClickHouse/pull/19960) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Add conversion of block structure for INSERT into Distributed tables if it does not match. [#19947](https://github.com/ClickHouse/ClickHouse/pull/19947) ([Azat Khuzhin](https://github.com/azat)).
* Improvement for the `system.distributed_ddl_queue` table. Initialize MaxDDLEntryID to the last value after restarting. Before this PR, MaxDDLEntryID will remain zero until a new DDLTask is processed. [#19924](https://github.com/ClickHouse/ClickHouse/pull/19924) ([Amos Bird](https://github.com/amosbird)).
* Show `MaterializeMySQL` tables in `system.parts`. [#19770](https://github.com/ClickHouse/ClickHouse/pull/19770) ([Stig Bakken](https://github.com/stigsb)).
* Add separate config directive for `Buffer` profile. [#19721](https://github.com/ClickHouse/ClickHouse/pull/19721) ([Azat Khuzhin](https://github.com/azat)).
* Move conditions that are not related to JOIN to WHERE clause. [#18720](https://github.com/ClickHouse/ClickHouse/issues/18720). [#19685](https://github.com/ClickHouse/ClickHouse/pull/19685) ([hexiaoting](https://github.com/hexiaoting)).
* Add ability to throttle INSERT into Distributed based on amount of pending bytes for async send (`bytes_to_delay_insert`/`max_delay_to_insert` and `bytes_to_throw_insert` settings for `Distributed` engine has been added). [#19673](https://github.com/ClickHouse/ClickHouse/pull/19673) ([Azat Khuzhin](https://github.com/azat)).
* Fix some rare cases when write errors can be ignored in destructors. [#19451](https://github.com/ClickHouse/ClickHouse/pull/19451) ([Azat Khuzhin](https://github.com/azat)).
* Print inline frames in stack traces for fatal errors. [#19317](https://github.com/ClickHouse/ClickHouse/pull/19317) ([Ivan](https://github.com/abyss7)).
#### Bug Fix

* Fix error `Bad cast from type ... to DB::ColumnLowCardinality` while inserting into table with `LowCardinality` column from `Values` format. Fixes #21140 [#21357](https://github.com/ClickHouse/ClickHouse/pull/21357) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
* Fix a deadlock in `ALTER DELETE` mutations for non replicated MergeTree table engines when the predicate contains the table itself. Fixes [#20558](https://github.com/ClickHouse/ClickHouse/issues/20558). [#21477](https://github.com/ClickHouse/ClickHouse/pull/21477) ([alesapin](https://github.com/alesapin)).
* Fix SIGSEGV for distributed queries on failures. [#21434](https://github.com/ClickHouse/ClickHouse/pull/21434) ([Azat Khuzhin](https://github.com/azat)).

* Now mutations allowed only for table engines that support them (MergeTree family, Memory, MaterializedView). Other engines will report a more clear error. Fixes [#21168](https://github.com/ClickHouse/ClickHouse/issues/21168). [#21183](https://github.com/ClickHouse/ClickHouse/pull/21183) ([alesapin](https://github.com/alesapin)).
* Fixes [#21112](https://github.com/ClickHouse/ClickHouse/issues/21112). Fixed bug that could cause duplicates with insert query (if one of the callbacks came a little too late). [#21138](https://github.com/ClickHouse/ClickHouse/pull/21138) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Fix `input_format_null_as_default` take effective when types are nullable. This fixes [#21116](https://github.com/ClickHouse/ClickHouse/issues/21116) . [#21121](https://github.com/ClickHouse/ClickHouse/pull/21121) ([Amos Bird](https://github.com/amosbird)).

* Fix type mismatch issue when using LowCardinality keys in joinGet. This fixes [#21114](https://github.com/ClickHouse/ClickHouse/issues/21114). [#21117](https://github.com/ClickHouse/ClickHouse/pull/21117) ([Amos Bird](https://github.com/amosbird)).
* fix default_replica_path and default_replica_name values are useless on Replicated(*)MergeTree engine when the engine needs specify other parameters. [#21060](https://github.com/ClickHouse/ClickHouse/pull/21060) ([mxzlxy](https://github.com/mxzlxy)).
* Out of bound memory access was possible when formatting specifically crafted out of range value of type `DateTime64`. This closes [#20494](https://github.com/ClickHouse/ClickHouse/issues/20494). This closes [#20543](https://github.com/ClickHouse/ClickHouse/issues/20543). [#21023](https://github.com/ClickHouse/ClickHouse/pull/21023) ([alexey-milovidov](https://github.com/alexey-milovidov)).
* Block parallel insertions into storage join. [#21009](https://github.com/ClickHouse/ClickHouse/pull/21009) ([vdimir](https://github.com/vdimir)).
* Fixed behaviour, when `ALTER MODIFY COLUMN` created mutation, that will knowingly fail. [#21007](https://github.com/ClickHouse/ClickHouse/pull/21007) ([Anton Popov](https://github.com/CurtizJ)).
* Closes [#9969](https://github.com/ClickHouse/ClickHouse/issues/9969). Fixed Brotli http compression error, which reproduced for large data sizes, slightly complicated structure and with json output format. Update Brotli to the latest version to include the "fix rare access to uninitialized data in ring-buffer". [#20991](https://github.com/ClickHouse/ClickHouse/pull/20991) ([Kseniia Sumarokova](https://github.com/kssenii)).

/** Custom memcpy implementation for ClickHouse.
* It has the following benefits over using glibc's implementation:
* 1. Avoiding dependency on specific version of glibc's symbol, like memcpy@@GLIBC_2.14 for portability.
* 2. Avoiding indirect call via PLT due to shared linking, that can be less efficient.
* 3. It's possible to include this header and call inline_memcpy directly for better inlining or interprocedural analysis.
* 4. Better results on our performance tests on current CPUs: up to 25% on some queries and up to 0.7%..1% in average across all queries.
*
* Writing our own memcpy is extremely difficult for the following reasons:
* 1. The optimal variant depends on the specific CPU model.
* 2. The optimal variant depends on the distribution of size arguments.
* 3. It depends on the number of threads copying data concurrently.
* 4. It also depends on how the calling code is using the copied data and how the different memcpy calls are related to each other.
* Due to vast range of scenarios it makes proper testing especially difficult.
* When writing our own memcpy there is a risk to overoptimize it
* on non-representative microbenchmarks while making real-world use cases actually worse.
*
* Most of the benchmarks for memcpy on the internet are wrong.
*
* Let's look at the details:
*
* For small size, the order of branches in code is important.
* There are variants with specific order of branches (like here or in glibc)
* or with jump table (in asm code see example from Cosmopolitan libc:
* https://github.com/jart/cosmopolitan/blob/de09bec215675e9b0beb722df89c6f794da74f3f/libc/nexgen32e/memcpy.S#L61)
* or with Duff device in C (see https://github.com/skywind3000/FastMemcpy/)
*
* It's also important how to copy uneven sizes.
* Almost every implementation, including this, is using two overlapping movs.
*
* It is important to disable -ftree-loop-distribute-patterns when compiling memcpy implementation,
* otherwise the compiler can replace internal loops to a call to memcpy that will lead to infinite recursion.
*
* For larger sizes it's important to choose the instructions used:
* - SSE or AVX or AVX-512;
* - rep movsb;
* Performance will depend on the size threshold, on the CPU model, on the "erms" flag
* ("Enhansed Rep MovS" - it indicates that performance of "rep movsb" is decent for large sizes)
* https://stackoverflow.com/questions/43343231/enhanced-rep-movsb-for-memcpy
*
* Using AVX-512 can be bad due to throttling.
* Using AVX can be bad if most code is using SSE due to switching penalty
* (it also depends on the usage of "vzeroupper" instruction).
* But in some cases AVX gives a win.
*
* It also depends on how many times the loop will be unrolled.
* We are unrolling the loop 8 times (by the number of available registers), but it not always the best.
*
* It also depends on the usage of aligned or unaligned loads/stores.
* We are using unaligned loads and aligned stores.
*
* It also depends on the usage of prefetch instructions. It makes sense on some Intel CPUs but can slow down performance on AMD.
* Setting up correct offset for prefetching is non-obvious.
*
* Non-temporary (cache bypassing) stores can be used for very large sizes (more than a half of L3 cache).
* But the exact threshold is unclear - when doing memcpy from multiple threads the optimal threshold can be lower,
* because L3 cache is shared (and L2 cache is partially shared).
*
* Very large size of memcpy typically indicates suboptimal (not cache friendly) algorithms in code or unrealistic scenarios,
* so we don't pay attention to using non-temporary stores.
*
* On recent Intel CPUs, the presence of "erms" makes "rep movsb" the most benefitial,
* even comparing to non-temporary aligned unrolled stores even with the most wide registers.
*
* memcpy can be written in asm, C or C++. The latter can also use inline asm.
* The asm implementation can be better to make sure that compiler won't make the code worse,
* to ensure the order of branches, the code layout, the usage of all required registers.
* But if it is located in separate translation unit, inlining will not be possible
* (inline asm can be used to overcome this limitation).
* Sometimes C or C++ code can be further optimized by compiler.
* For example, clang is capable replacing SSE intrinsics to AVX code if -mavx is used.
*
* Please note that compiler can replace plain code to memcpy and vice versa.
* - memcpy with compile-time known small size is replaced to simple instructions without a call to memcpy;
* it is controlled by -fbuiltin-memcpy and can be manually ensured by calling __builtin_memcpy.
* This is often used to implement unaligned load/store without undefined behaviour in C++.
* - a loop with copying bytes can be recognized and replaced by a call to memcpy;
* it is controlled by -ftree-loop-distribute-patterns.
* - also note that a loop with copying bytes can be unrolled, peeled and vectorized that will give you
* inline code somewhat similar to a decent implementation of memcpy.
*
* This description is up to date as of Mar 2021.
*
* How to test the memcpy implementation for performance:
* 1. Test on real production workload.
* 2. For synthetic test, see utils/memcpy-bench, but make sure you will do the best to exhaust the wide range of scenarios.
*
* TODO: Add self-tuning memcpy with bayesian bandits algorithm for large sizes.
* See https://habr.com/en/company/yandex/blog/457612/

Internal implementation of `memcpy` function.
It has the following advantages over `libc`-supplied implementation:
- it is linked statically, so the function is called directly, not through a `PLT` (procedure lookup table of shared library);
- it is linked statically, so the function can have position-dependent code;
- your binaries will not depend on `glibc`'s memcpy, that forces dependency on specific symbol version like `memcpy@@GLIBC_2.14` and consequently on specific version of `glibc` library;
- you can include `memcpy.h` directly and the function has the chance to be inlined, which is beneficial for small but unknown at compile time sizes of memory regions;
- this version of `memcpy` pretend to be faster (in our benchmarks, the difference is within few percents).
Currently it uses the implementation from **Linwei** (skywind3000@163.com).
Look at https://www.zhihu.com/question/35172305 for discussion.
Drawbacks:
- only use SSE 2, doesn't use wider (AVX, AVX 512) vector registers when available;
- no CPU dispatching; doesn't take into account actual cache size.
Also worth to look at:
- simple implementation from Facebook: https://github.com/facebook/folly/blob/master/folly/memcpy.S
- implementation from Agner Fog: http://www.agner.org/optimize/
- glibc source code.

# PosgtreSQL {#postgresql}
The PostgreSQL engine allows you to perform `SELECT` queries on data that is stored on a remote PostgreSQL server.
## Creating a Table {#creating-a-table}
``` sql
CREATE TABLE [IF NOT EXISTS] [db.]table_name [ON CLUSTER cluster]
(
name1 [type1] [DEFAULT|MATERIALIZED|ALIAS expr1] [TTL expr1],
name2 [type2] [DEFAULT|MATERIALIZED|ALIAS expr2] [TTL expr2],
...
) ENGINE = PostgreSQL('host:port', 'database', 'table', 'user', 'password');
```
See a detailed description of the [CREATE TABLE](../../../sql-reference/statements/create/table.md#create-table-query) query.
The table structure can differ from the original PostgreSQL table structure:
- Column names should be the same as in the original PostgreSQL table, but you can use just some of these columns and in any order.
- Column types may differ from those in the original PostgreSQL table. ClickHouse tries to [cast](../../../sql-reference/functions/type-conversion-functions.md#type_conversion_function-cast) values to the ClickHouse data types.
- Setting `external_table_functions_use_nulls` defines how to handle Nullable columns. Default is 1, if 0 - table function will not make nullable columns and will insert default values instead of nulls. This is also applicable for null values inside array data types.
**Engine Parameters**
- `host:port` — PostgreSQL server address.
- `database` — Remote database name.
- `table` — Remote table name.
- `user` — PostgreSQL user.
- `password` — User password.
SELECT Queries on PostgreSQL side run as `COPY (SELECT ...) TO STDOUT` inside read-only PostgreSQL transaction with commit after each `SELECT` query.
Simple `WHERE` clauses such as `=, !=, >, >=, <, <=, IN` are executed on the PostgreSQL server.
All joins, aggregations, sorting, `IN [ array ]` conditions and the `LIMIT` sampling constraint are executed in ClickHouse only after the query to PostgreSQL finishes.
INSERT Queries on PostgreSQL side run as `COPY "table_name" (field1, field2, ... fieldN) FROM STDIN` inside PostgreSQL transaction with auto-commit after each `INSERT` statement.
PostgreSQL Array types converts into ClickHouse arrays.
Be careful in PostgreSQL an array data created like a type_name[] may contain multi-dimensional arrays of different dimensions in different table rows in same column, but in ClickHouse it is only allowed to have multidimensional arrays of the same count of dimensions in all table rows in same column.
## Usage Example {#usage-example}
Table in PostgreSQL:
``` text
postgres=# CREATE TABLE "public"."test" (
"int_id" SERIAL,
"int_nullable" INT NULL DEFAULT NULL,
"float" FLOAT NOT NULL,
"str" VARCHAR(100) NOT NULL DEFAULT '',
"float_nullable" FLOAT NULL DEFAULT NULL,
PRIMARY KEY (int_id));
CREATE TABLE
postgres=# insert into test (int_id, str, "float") VALUES (1,'test',2);
INSERT 0 1
postgresql> select * from test;
int_id | int_nullable | float | str | float_nullable
--------+--------------+-------+------+----------------
1 | | 2 | test |
(1 row)
```
Table in ClickHouse, retrieving data from the PostgreSQL table created above:
``` sql
CREATE TABLE default.postgresql_table
(
`float_nullable` Nullable(Float32),
`str` String,
`int_id` Int32
)
ENGINE = PostgreSQL('localhost:5432', 'public', 'test', 'postges_user', 'postgres_password');
```
``` sql
SELECT * FROM postgresql_table WHERE str IN ('test')
```
``` text
┌─float_nullable─┬─str──┬─int_id─┐
│ ᴺᵁᴸᴸ │ test │ 1 │
└────────────────┴──────┴────────┘
1 rows in set. Elapsed: 0.019 sec.
```

### Details {#details}
In the case of `MergeTree` tables, data is getting to disk in different ways:
- As a result of an insert (`INSERT` query).
- During background merges and [mutations](../../../sql-reference/statements/alter/index.md#alter-mutations).
- When downloading from another replica.
- As a result of partition freezing [ALTER TABLE … FREEZE PARTITION](../../../sql-reference/statements/alter/partition.md#alter_freeze-partition).
In all these cases except for mutations and partition freezing, a part is stored on a volume and a disk according to the given storage policy:
1. The first volume (in the order of definition) that has enough disk space for storing a part (`unreserved_space > current_part_size`) and allows for storing parts of a given size (`max_data_part_size_bytes > current_part_size`) is chosen.
2. Within this volume, that disk is chosen that follows the one, which was used for storing the previous chunk of data, and that has free space more than the part size (`unreserved_space - keep_free_space_bytes > current_part_size`).
Under the hood, mutations and partition freezing make use of [hard links](https://en.wikipedia.org/wiki/Hard_link). Hard links between different disks are not supported, therefore in such cases the resulting parts are stored on the same disks as the initial ones.
In the background, parts are moved between volumes on the basis of the amount of free space (`move_factor` parameter) according to the order the volumes are declared in the configuration file.
Data is never transferred from the last one and into the first one. One may use system tables [system.part_log](../../../operations/system-tables/part_log.md#system_tables-part-log) (field `type = MOVE_PART`) and [system.parts](../../../operations/system-tables/parts.md#system_tables-parts) (fields `path` and `disk`) to monitor background moves. Also, the detailed information can be found in server logs.
User can force moving a part or a partition from one volume to another using the query [ALTER TABLE … MOVE PART\|PARTITION … TO VOLUME\|DISK …](../../../sql-reference/statements/alter/partition.md#alter_move-partition), all the restrictions for background operations are taken into account. The query initiates a move on its own and does not wait for background operations to be completed. User will get an error message if not enough free space is available or if any of the required conditions are not met.
Moving data does not interfere with data replication. Therefore, different storage policies can be specified for the same table on different replicas.
After the completion of background merges and mutations, old parts are removed only after a certain amount of time (`old_parts_lifetime`).
During this time, they are not moved to other volumes or disks. Therefore, until the parts are finally removed, they are still taken into account for evaluation of the occupied disk space.

In order to achieve this, specify previously defined LDAP server name (see [LDAP Server Definition](#ldap-server-definition)) in an `ldap` section inside the `users_directories` section of the `config.xml` file.
At each login attempt, ClickHouse will try to find the user definition locally and authenticate it as usual, but if the user is not defined, ClickHouse will assume it exists in the external LDAP directory, and will try to "bind" to the specified DN at the LDAP server using the provided credentials. If successful, the user will be considered existing and authenticated. The user will be assigned roles from the list specified in the `roles` section.
