## 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"
```

# 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.
## Create Table {#creating-a-table}
``` sql
CREATE TABLE s3_queue_engine_table (name String, value UInt32)
ENGINE = S3Queue(path [, NOSIGN | aws_access_key_id, aws_secret_access_key,] format, [compression])
[SETTINGS]
[mode = 'unordered',]
[after_processing = 'keep',]
[keeper_path = '',]
[s3queue_loading_retries = 0,]
[s3queue_polling_min_timeout_ms = 1000,]
[s3queue_polling_max_timeout_ms = 10000,]
[s3queue_polling_backoff_ms = 0,]
[s3queue_tracked_files_limit = 1000,]
[s3queue_tracked_file_ttl_sec = 0,]
[s3queue_polling_size = 50,]
```
**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.
**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 = 'ordred';
```
Using named collections:
``` xml
<clickhouse>
<named_collections>
<s3queue_conf>
<url>'https://clickhouse-public-datasets.s3.amazonaws.com/my-test-bucket-768/*</url>
<access_key_id>test<access_key_id>
<secret_access_key>test</secret_access_key>
</s3queue_conf>
</named_collections>
</clickhouse>
```
```sql
CREATE TABLE s3queue_engine_table (name String, value UInt32)
ENGINE=S3Queue(s3queue_conf, format = 'CSV', compression_method = 'gzip')
SETTINGS
mode = 'ordred';
```
## Settings {#s3queue-settings}
### mode {#mode}
Possible values:
- unordered — With unordered mode, the set of all already processed files is tracked with persistent nodes in ZooKeeper.
- ordered — With ordered mode, only the max name of the successfully consumed file, and the names of files that will be retried after unsuccessful loading attempt are being stored in ZooKeeper.
Default value: `unordered`.
### after_processing {#after_processing}
Delete or keep file after successful processing.
Possible values:
- keep.
- delete.
Default value: `keep`.
### keeper_path {#keeper_path}
The path in ZooKeeper can be specified as a table engine setting or default path can be formed from the global configuration-provided path and table UUID.
Possible values:
- String.
Default value: `/`.
### s3queue_loading_retries {#s3queue_loading_retries}
Retry file loading up to specified number of times. By default, there are no retries.
Possible values:
- Positive integer.
Default value: `0`.
### s3queue_polling_min_timeout_ms {#s3queue_polling_min_timeout_ms}
Minimal timeout before next polling (in milliseconds).
Possible values:
- Positive integer.
Default value: `1000`.
### s3queue_polling_max_timeout_ms {#s3queue_polling_max_timeout_ms}
Maximum timeout before next polling (in milliseconds).
Possible values:
- Positive integer.
Default value: `10000`.
### s3queue_polling_backoff_ms {#s3queue_polling_backoff_ms}
Polling backoff (in milliseconds).
Possible values:
- Positive integer.
Default value: `0`.
### s3queue_tracked_files_limit {#s3queue_tracked_files_limit}
Allows to limit the number of Zookeeper nodes if the 'unordered' mode is used, does nothing for 'ordered' mode.
If limit reached the oldest processed files will be deleted from ZooKeeper node and processed again.
Possible values:
- Positive integer.
Default value: `1000`.
### s3queue_tracked_file_ttl_sec {#s3queue_tracked_file_ttl_sec}
Maximum number of seconds to store processed files in ZooKeeper node (store forever by default) for 'unordered' mode, does nothing for 'ordered' mode.
After the specified number of seconds, the file will be re-imported.
Possible values:
- Positive integer.
Default value: `0`.
### s3queue_polling_size {#s3queue_polling_size}
Maximum files to fetch from S3 with SELECT or in background task.
Engine takes files for processing from S3 in batches.
We limit the batch size to increase concurrency if multiple table engines with the same `keeper_path` consume files from the same path.
Possible values:
- Positive integer.
Default value: `50`.
## 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 `?`.

### 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:
```sql
SELECT * FROM test.hits format CapnProto SETTINGS format_capn_proto_use_autogenerated_schema=1, output_format_schema='path/to/schema/schema.capnp'
```
In this case autogenerated CapnProto schema will be saved in file `path/to/schema/schema.capnp`.

```bash
$ cat hits.bin | clickhouse-client --query "INSERT INTO test.hits SETTINGS format_protobuf_use_autogenerated_schema=1 FORMAT Protobuf"
```
The setting [format_protobuf_use_autogenerated_schema](../operations/settings/settings-formats.md#format_protobuf_use_autogenerated_schema) is enabled by default and applies if [format_schema](../operations/settings/settings-formats.md#formatschema-format-schema) is not set.

```
In this case autogenerated Protobuf schema will be saved in file `path/to/schema/schema.capnp`.

# 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.

## precise_float_parsing {#precise_float_parsing}
Switches [Float32/Float64](../../sql-reference/data-types/float.md) parsing algorithms:
* If the value is `1`, then precise method is used. It is slower than fast method, but it always returns a number that is the closest machine representable number to the input.
* Otherwise, fast method is used (default). It usually returns the same value as precise, but in rare cases result may differ by one or two least significant digits.
Possible values: `0`, `1`.
Default value: `0`.
Example:
```sql
SELECT toFloat64('1.7091'), toFloat64('1.5008753E7') SETTINGS precise_float_parsing = 0;
┌─toFloat64('1.7091')─┬─toFloat64('1.5008753E7')─┐

## precise_float_parsing {#precise_float_parsing}
Позволяет выбрать алгоритм, используемый при парсинге [Float32/Float64](../../sql-reference/data-types/float.md):
* Если установлено значение `1`, то используется точный метод. Он более медленный, но всегда возвращает число, наиболее близкое к входному значению.
* В противном случае используется быстрый метод (поведение по умолчанию). Обычно результат его работы совпадает с результатом, полученным точным методом, однако в редких случаях он может отличаться на 1 или 2 наименее значимых цифры.
Возможные значения: `0`, `1`.
Значение по умолчанию: `0`.
Пример:
```sql
SELECT toFloat64('1.7091'), toFloat64('1.5008753E7') SETTINGS precise_float_parsing = 0;
