# Iceberg Table Engine

This engine provides a read-only integration with existing Apache [Iceberg](https://iceberg.apache.org/) tables in Amazon S3, Azure and locally stored tables.

## Create Table

Note that the Iceberg table must already exist in the storage, this command does not take DDL parameters to create a new table.

``` sql
CREATE TABLE iceberg_table_s3
    ENGINE = IcebergS3(url,  [, NOSIGN | access_key_id, secret_access_key, [session_token]], format, [,compression])

CREATE TABLE iceberg_table_azure
    ENGINE = IcebergAzure(connection_string|storage_account_url, container_name, blobpath, [account_name, account_key, format, compression])

CREATE TABLE iceberg_table_local
    ENGINE = IcebergLocal(path_to_table, [,format] [,compression_method])
```

**Engine arguments**

Description of the arguments coincides with description of arguments in engines `S3`, `AzureBlobStorage` and `File` correspondingly.
`format` stands for the format of data files in the Iceberg table.

Engine parameters can be specified using [Named Collections](../../../operations/named-collections.md)

**Example**

```sql
CREATE TABLE iceberg_table ENGINE=IcebergS3('http://test.s3.amazonaws.com/clickhouse-bucket/test_table', 'test', 'test')
```

Using named collections:

``` xml
<clickhouse>
    <named_collections>
        <iceberg_conf>
            <url>http://test.s3.amazonaws.com/clickhouse-bucket/</url>
            <access_key_id>test</access_key_id>
            <secret_access_key>test</secret_access_key>
        </iceberg_conf>
    </named_collections>
</clickhouse>
```

```sql
CREATE TABLE iceberg_table ENGINE=IcebergS3(iceberg_conf, filename = 'test_table')

```

**Aliases**


Table engine `Iceberg` is an alias to `IcebergS3` now.
