| Name | Type/Value | Description |

| default_db_config| [CRDB database_config](https://redis.io/docs/latest/operate/rs/references/rest-api/objects/crdb/database_config) object | Default database configuration applied to all instances in the CRDB object. In most cases, instances should use the same configuration. If you need to override `default_db_config` or add configuration values for specific instances, you can use `db_config` in individual [instance objects](https://redis.io/docs/latest/operate/rs/references/rest-api/objects/crdb/instance_info). For a list of which settings must be identical across all instances and which to set per instance, see the [CRDB database config object](https://redis.io/docs/latest/operate/rs/references/rest-api/objects/crdb/database_config) reference. |
