``` sql
CREATE TABLE s3_engine_table (name String, value UInt32)
ENGINE = S3(path, [aws_access_key_id, aws_secret_access_key,] format, structure, [compression])
ENGINE = S3(path, [aws_access_key_id, aws_secret_access_key,] format, [compression])
```
**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).
- `format` — The [format](../../../interfaces/formats.md#formats) of the file.
- `structure` — Structure of the table. Format `'column1_name column1_type, column2_name column2_type, ...'`.
- `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.

1. Set up the `s3_engine_table` table:
``` sql
CREATE TABLE s3_engine_table (name String, value UInt32) ENGINE=S3('https://storage.yandexcloud.net/my-test-bucket-768/test-data.csv.gz', 'CSV', 'name String, value UInt32', 'gzip');
CREATE TABLE s3_engine_table (name String, value UInt32) ENGINE=S3('https://storage.yandexcloud.net/my-test-bucket-768/test-data.csv.gz', 'CSV', 'gzip');
```
2. Fill file:

**Параметры движка**
- `path` — URL-адрес бакета с указанием пути к файлу. Поддерживает следующие подстановочные знаки в режиме "только чтение": `*`, `?`, `{abc,def}` и `{N..M}` где `N`, `M` — числа, `'abc'`, `'def'` — строки. Подробнее смотри [ниже](#wildcards-in-path).
- `format` — [формат](../../../interfaces/formats.md#formats) файла.
- `structure` — структура таблицы в формате `'column1_name column1_type, column2_name column2_type, ...'`.
- `compression` — тип сжатия. Возможные значения: `none`, `gzip/gz`, `brotli/br`, `xz/LZMA`, `zstd/zst`. Необязательный параметр. Если не указано, то тип сжатия определяется автоматически по расширению файла.
**Пример**
``` sql
CREATE TABLE s3_engine_table (name String, value UInt32)
ENGINE = S3('https://storage.yandexcloud.net/my-test-bucket-768/test-data.csv.gz', 'CSV', 'name String, value UInt32', 'gzip');
ENGINE = S3('https://storage.yandexcloud.net/my-test-bucket-768/test-data.csv.gz', 'CSV', 'gzip');
INSERT INTO s3_engine_table VALUES ('one', 1), ('two', 2), ('three', 3);
SELECT * FROM s3_engine_table LIMIT 2;
