# CreateDatabaseRequest
## Properties
**default_catalog** | Option<**String**> | Optional name the database's auto-created default catalog answers to inside its query scope. Must be a valid SQL identifier (`[a-z0-9_]`, not starting with a digit) and may not collide with the system catalogs `hotdata`, `datasets`, or `information_schema`. Defaults to `default` when omitted, so `default.main.<table>` keeps working. | [optional]
**expires_at** | Option<**String**> | When this database expires. Accepts either an RFC 3339 timestamp (e.g. `\"2026-06-01T00:00:00Z\"`) or a relative duration suffixed with `h` (hours), `m` (minutes), or `d` (days) — for example `\"24h\"`, `\"48h\"`, or `\"7d\"`. Omitted (or empty) means the database never expires. Expiry is best-effort: the database will not be deleted before `expires_at`, but cleanup may run later than the exact timestamp. | [optional]
**name** | Option<**String**> | Optional free-form display label (for UIs/CLIs). Not unique. Not an identifier — databases are always addressed by `id`. Accepts the legacy `description` key as an alias so clients that predate the rename keep populating this field. | [optional]
**schemas** | Option<[**Vec<models::DatabaseDefaultSchemaDecl>**](DatabaseDefaultSchemaDecl.md)> | Optional schemas/tables to declare on the database's auto-created default catalog. Mirrors the `config.schemas` field of a managed `POST /v1/connections`. Tables declared here can be loaded via the standard managed-table load endpoint targeting `default_connection_id`. Omitted or empty means the default catalog starts empty. | [optional]
**storage_backend** | Option<**String**> | Physical storage backend for the database's auto-created `default` catalog. `\"parquet\"` (default) uses the versioned parquet cache. `\"ducklake\"` stores data in a DuckLake catalog in the shared metadata DB configured via `ducklake.metadata_pg_url`, which must be configured for that value to be accepted. Omitted means `\"parquet\"`. | [optional]
