+#### Multi catalog support
+
+The Gravitino Iceberg REST server supports multiple catalogs and offers a
configuration-based catalog management system.
+
+| Configuration item | Description
| Default value | Required | Since Version |
+|----------------------------------------------|------------------------------------------------------------------------------------------------------------------|-----------------------------|----------|---------------|
+| `gravitino.iceberg-rest.catalog-provider` | The implementation of
IcebergTableOpsProvider defines how the Iceberg REST catalog server gets
Iceberg catalogs. | `config-based-provider` | No | 0.7.0 |
+
+When using a config-based catalog provider, you can configure the default
catalog with gravitino.iceberg-rest.catalog.<param name>=<value>. For specific
catalogs, use the format gravitino.iceberg-rest.catalog.<catalog name>.<param
name>=<value>.
Review Comment:
use ` for special names, like `gravitino.iceberg-rest.catalog.<param
name>=<value>`, `gravitino.iceberg-rest.catalog.<catalog name>.<param
name>=<value>`, `prefix`, `hive_backend` `jdbc_backend`
