### ClickHouse release v23.7.2.25-stable (8dd1107b032) FIXME as compared to v23.7.1.2470-stable (a70127baecc)
|
||||
|
||||
#### Backward Incompatible Change
|
||||
* Backported in [#52850](https://github.com/ClickHouse/ClickHouse/issues/52850): If a dynamic disk contains a name, it should be specified as `disk = disk(name = 'disk_name'`, ...) in disk function arguments. In previous version it could be specified as `disk = disk_<disk_name>(...)`, which is no longer supported. [#52820](https://github.com/ClickHouse/ClickHouse/pull/52820) ([Kseniia Sumarokova](https://github.com/kssenii)).
|
||||
|
||||
#### Build/Testing/Packaging Improvement
|
||||
* Backported in [#52913](https://github.com/ClickHouse/ClickHouse/issues/52913): Add `clickhouse-keeper-client` symlink to the clickhouse-server package. [#51882](https://github.com/ClickHouse/ClickHouse/pull/51882) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).
|
||||
|
||||
#### Bug Fix (user-visible misbehavior in an official stable release)
|
||||
|
||||
* Fix binary arithmetic for Nullable(IPv4) [#51642](https://github.com/ClickHouse/ClickHouse/pull/51642) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
|
||||
* Support IPv4 and IPv6 as dictionary attributes [#51756](https://github.com/ClickHouse/ClickHouse/pull/51756) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
|
||||
* init and destroy ares channel on demand.. [#52634](https://github.com/ClickHouse/ClickHouse/pull/52634) ([Arthur Passos](https://github.com/arthurpassos)).
|
||||
* Fix crash in function `tuple` with one sparse column argument [#52659](https://github.com/ClickHouse/ClickHouse/pull/52659) ([Anton Popov](https://github.com/CurtizJ)).
|
||||
* Fix data race in Keeper reconfiguration [#52804](https://github.com/ClickHouse/ClickHouse/pull/52804) ([Antonio Andelic](https://github.com/antonio2368)).
|
||||
* clickhouse-keeper: fix implementation of server with poll() [#52833](https://github.com/ClickHouse/ClickHouse/pull/52833) ([Andy Fiddaman](https://github.com/citrus-it)).
|
||||
|
||||
#### NOT FOR CHANGELOG / INSIGNIFICANT
|
||||
|
||||
* Rename setting disable_url_encoding to enable_url_encoding and add a test [#52656](https://github.com/ClickHouse/ClickHouse/pull/52656) ([Kruglov Pavel](https://github.com/Avogar)).
|
||||
* Fix bugs and better test for SYSTEM STOP LISTEN [#52680](https://github.com/ClickHouse/ClickHouse/pull/52680) ([Nikolay Degterinsky](https://github.com/evillique)).
|
||||
* Increase min protocol version for sparse serialization [#52835](https://github.com/ClickHouse/ClickHouse/pull/52835) ([Anton Popov](https://github.com/CurtizJ)).
|
||||
* Docker improvements [#52869](https://github.com/ClickHouse/ClickHouse/pull/52869) ([Mikhail f. Shiryaev](https://github.com/Felixoid)).

## Building in docker
|
||||
We use the docker image `clickhouse/binary-builder` for our CI builds. It contains everything necessary to build the binary and packages. There is a script `docker/packager/packager` to ease the image usage:
|
||||
|
||||
```bash
|
||||
# define a directory for the output artifacts
|
||||
output_dir="build_results"
|
||||
# a simplest build
|
||||
./docker/packager/packager --package-type=binary --output-dir "$output_dir"
|
||||
# build debian packages
|
||||
./docker/packager/packager --package-type=deb --output-dir "$output_dir"
|
||||
# by default, debian packages use thin LTO, so we can override it to speed up the build
|
||||
CMAKE_FLAGS='-DENABLE_THINLTO=' ./docker/packager/packager --package-type=deb --output-dir "./$(git rev-parse --show-cdup)/build_results"

When creating a new replica of the database, this replica creates tables by itself. If the replica has been unavailable for a long time and has lagged behind the replication log — it checks its local metadata with the current metadata in ZooKeeper, moves the extra tables with data to a separate non-replicated database (so as not to accidentally delete anything superfluous), creates the missing tables, updates the table names if they have been renamed. The data is replicated at the `ReplicatedMergeTree` level, i.e. if the table is not replicated, the data will not be replicated (the database is responsible only for metadata).

|
||||
[`ALTER TABLE ATTACH|FETCH|DROP|DROP DETACHED|DETACH PARTITION|PART`](../../sql-reference/statements/alter/partition.md) queries are allowed but not replicated. The database engine will only add/fetch/remove the partition/part to the current replica. However, if the table itself uses a Replicated table engine, then the data will be replicated after using `ATTACH`.

# S3Queue Table Engine
|
||||
This engine provides integration with [Amazon S3](https://aws.amazon.com/s3/) ecosystem and allows streaming import. This engine is similar to the [Kafka](../../../engines/table-engines/integrations/kafka.md), [RabbitMQ](../../../engines/table-engines/integrations/rabbitmq.md) engines, but provides S3-specific features.
|
||||
|
||||

```
|
||||
|
||||
**Engine parameters**
|
||||
|
||||
- `path` — Bucket url with path to file. Supports following wildcards in readonly mode: `*`, `?`, `{abc,def}` and `{N..M}` where `N`, `M` — numbers, `'abc'`, `'def'` — strings. For more information see [below](#wildcards-in-path).
|
||||
- `NOSIGN` - If this keyword is provided in place of credentials, all the requests will not be signed.
|
||||
- `format` — The [format](../../../interfaces/formats.md#formats) of the file.
|
||||
- `aws_access_key_id`, `aws_secret_access_key` - Long-term credentials for the [AWS](https://aws.amazon.com/) account user. You can use these to authenticate your requests. Parameter is optional. If credentials are not specified, they are used from the configuration file. For more information see [Using S3 for Data Storage](../mergetree-family/mergetree.md#table_engine-mergetree-s3).
|
||||
- `compression` — Compression type. Supported values: `none`, `gzip/gz`, `brotli/br`, `xz/LZMA`, `zstd/zst`. Parameter is optional. By default, it will autodetect compression by file extension.
|
||||

|
||||
|
||||
|
||||
## S3-related Settings {#s3-settings}
|
||||
|
||||
Engine supports all s3 related settings. For more information about S3 settings see [here](../../../engines/table-engines/integrations/s3.md).
|
||||
|
||||
|
||||
## Description {#description}
|
||||
|
||||
`SELECT` is not particularly useful for streaming import (except for debugging), because each file can be imported only once. It is more practical to create real-time threads using [materialized views](../../../sql-reference/statements/create/view.md). To do this:
|
||||
|
||||
1. Use the engine to create a table for consuming from specified path in S3 and consider it a data stream.
|
||||
2. Create a table with the desired structure.
|
||||
3. Create a materialized view that converts data from the engine and puts it into a previously created table.
|
||||
|
||||
When the `MATERIALIZED VIEW` joins the engine, it starts collecting data in the background.
|
||||
|
||||
Example:
|
||||
|
||||
``` sql
|
||||
CREATE TABLE s3queue_engine_table (name String, value UInt32)
|
||||
ENGINE=S3Queue('https://clickhouse-public-datasets.s3.amazonaws.com/my-test-bucket-768/*', 'CSV', 'gzip')
|
||||
SETTINGS
|
||||
mode = 'unordred',
|
||||
keeper_path = '/clickhouse/s3queue/';
|
||||
|
||||
CREATE TABLE stats (name String, value UInt32)
|
||||
ENGINE = MergeTree() ORDER BY name;
|
||||
|
||||
CREATE MATERIALIZED VIEW consumer TO stats
|
||||
AS SELECT name, value FROM s3queue_engine_table;
|
||||
|
||||
SELECT * FROM stats ORDER BY name;
|
||||
```
|
||||
|
||||
## Virtual columns {#virtual-columns}
|
||||
|
||||
- `_path` — Path to the file.
|
||||
- `_file` — Name of the file.
|
||||
|
||||
For more information about virtual columns see [here](../../../engines/table-engines/index.md#table_engines-virtual_columns).
|
||||
|
||||
|
||||
## Wildcards In Path {#wildcards-in-path}
|
||||
|
||||
`path` argument can specify multiple files using bash-like wildcards. For being processed file should exist and match to the whole path pattern. Listing of files is determined during `SELECT` (not at `CREATE` moment).
|
||||
|
||||
- `*` — Substitutes any number of any characters except `/` including empty string.
|
||||
- `?` — Substitutes any single character.
|
||||
- `{some_string,another_string,yet_another_one}` — Substitutes any of strings `'some_string', 'another_string', 'yet_another_one'`.
|
||||
- `{N..M}` — Substitutes any number in range from N to M including both borders. N and M can have leading zeroes e.g. `000..078`.
|
||||
|
||||
Constructions with `{}` are similar to the [remote](../../../sql-reference/table-functions/remote.md) table function.
|
||||
|
||||
:::note
|
||||
If the listing of files contains number ranges with leading zeros, use the construction with braces for each digit separately or use `?`.

|

`L2Distance` is also called Euclidean distance, the Euclidean distance between two points in Euclidean space is the length of a line segment between the two points.

For example: If we have point P(p1,p2), Q(q1,q2), their distance will be d(p,q)
|
||||
|
||||
|

`cosineDistance` also called cosine similarity is a measure of similarity between two non-zero vectors defined in an inner product space. Cosine similarity is the cosine of the angle between the vectors; that is, it is the dot product of the vectors divided by the product of their lengths.
|
||||
|
||||
|
||||
The Euclidean distance corresponds to the L2-norm of a difference between vectors. The cosine similarity is proportional to the dot product of two vectors and inversely proportional to the product of their magnitudes.
|

|

In one sentence: cosine similarity care only about the angle between them, but do not care about the "distance" we normally think.

### Using autogenerated schema {#using-autogenerated-capn-proto-schema}
|
||||
|
||||
If you don't have an external CapnProto schema for your data, you can still output/input data in CapnProto format using autogenerated schema.
|
||||
For example:
|
||||
|
||||
```sql
|
||||
SELECT * FROM test.hits format CapnProto SETTINGS format_capn_proto_use_autogenerated_schema=1
|
||||
```
|
||||
|
||||
In this case ClickHouse will autogenerate CapnProto schema according to the table structure using function [structureToCapnProtoSchema](../sql-reference/functions/other-functions.md#structure_to_capn_proto_schema) and will use this schema to serialize data in CapnProto format.
|
||||
|
||||
You can also read CapnProto file with autogenerated schema (in this case the file must be created using the same schema):
|
||||
|
||||
```bash
|
||||
$ cat hits.bin | clickhouse-client --query "INSERT INTO test.hits SETTINGS format_capn_proto_use_autogenerated_schema=1 FORMAT CapnProto"
|
||||
```
|
||||
|
||||
The setting [format_capn_proto_use_autogenerated_schema](../operations/settings/settings-formats.md#format_capn_proto_use_autogenerated_schema) is enabled by default and applies if [format_schema](../operations/settings/settings-formats.md#formatschema-format-schema) is not set.
|
||||
|
||||
You can also save autogenerated schema in the file during input/output using setting [output_format_schema](../operations/settings/settings-formats.md#outputformatschema-output-format-schema). For example:

# Profile Guided Optimization
|
||||
|
||||
Profile-Guided Optimization (PGO) is a compiler optimization technique where a program is optimized based on the runtime profile.
|
||||
|
||||
According to the tests, PGO helps with achieving better performance for ClickHouse. According to the tests, we see improvements up to 15% in QPS on the ClickBench test suite. The more detailed results are available [here](https://pastebin.com/xbue3HMU). The performance benefits depend on your typical workload - you can get better or worse results.
|
||||
|
||||
More information about PGO in ClickHouse you can read in the corresponding GitHub [issue](https://github.com/ClickHouse/ClickHouse/issues/44567).
|
||||
|
||||
## How to build ClickHouse with PGO?
|
||||
|
||||
There are two major kinds of PGO: [Instrumentation](https://clang.llvm.org/docs/UsersManual.html#using-sampling-profilers) and [Sampling](https://clang.llvm.org/docs/UsersManual.html#using-sampling-profilers) (also known as AutoFDO). In this guide is described the Instrumentation PGO with ClickHouse.
|
||||
|
||||
1. Build ClickHouse in Instrumented mode. In Clang it can be done via passing `-fprofile-instr-generate` option to `CXXFLAGS`.
|
||||
2. Run instrumented ClickHouse on a sample workload. Here you need to use your usual workload. One of the approaches could be using [ClickBench](https://github.com/ClickHouse/ClickBench) as a sample workload. ClickHouse in the instrumentation mode could work slowly so be ready for that and do not run instrumented ClickHouse in performance-critical environments.
|
||||
3. Recompile ClickHouse once again with `-fprofile-instr-use` compiler flags and profiles that are collected from the previous step.
|
||||
|
||||
A more detailed guide on how to apply PGO is in the Clang [documentation](https://clang.llvm.org/docs/UsersManual.html#profile-guided-optimization).
|
||||
|
||||
If you are going to collect a sample workload directly from a production environment, we recommend trying to use Sampling PGO.
