    Body param: Updates compaction configuration (all fields optional).

    - `State MaintenanceConfigUpdateParamsCompactionState`

      Updates the state optionally.

      - `const MaintenanceConfigUpdateParamsCompactionStateEnabled MaintenanceConfigUpdateParamsCompactionState = "enabled"`

      - `const MaintenanceConfigUpdateParamsCompactionStateDisabled MaintenanceConfigUpdateParamsCompactionState = "disabled"`

    - `TargetSizeMB MaintenanceConfigUpdateParamsCompactionTargetSizeMB`

      - `const MaintenanceConfigUpdateParamsCompactionTargetSizeMB512 MaintenanceConfigUpdateParamsCompactionTargetSizeMB = "512"`

  - `SnapshotExpiration param.Field[MaintenanceConfigUpdateParamsSnapshotExpiration]`

    Body param: Updates snapshot expiration configuration (all fields optional).

    - `MaxSnapshotAge string`

      Updates the maximum age for snapshots optionally.

    - `MinSnapshotsToKeep int64`

      Updates the minimum number of snapshots to retain optionally.

    - `State MaintenanceConfigUpdateParamsSnapshotExpirationState`

      Updates the state optionally.

      - `const MaintenanceConfigUpdateParamsSnapshotExpirationStateEnabled MaintenanceConfigUpdateParamsSnapshotExpirationState = "enabled"`

      - `const MaintenanceConfigUpdateParamsSnapshotExpirationStateDisabled MaintenanceConfigUpdateParamsSnapshotExpirationState = "disabled"`

### Returns

- `type MaintenanceConfigUpdateResponse struct{…}`

  Configures maintenance for the catalog.

  - `Compaction MaintenanceConfigUpdateResponseCompaction`

    Configures compaction for catalog maintenance.

      Specifies the state of maintenance operations.

      - `const MaintenanceConfigUpdateResponseCompactionStateEnabled MaintenanceConfigUpdateResponseCompactionState = "enabled"`

      - `const MaintenanceConfigUpdateResponseCompactionStateDisabled MaintenanceConfigUpdateResponseCompactionState = "disabled"`

    - `TargetSizeMB MaintenanceConfigUpdateResponseCompactionTargetSizeMB`

      Sets the target file size for compaction in megabytes. Defaults to "128".

      - `const MaintenanceConfigUpdateResponseCompactionTargetSizeMB64 MaintenanceConfigUpdateResponseCompactionTargetSizeMB = "64"`

      - `const MaintenanceConfigUpdateResponseCompactionTargetSizeMB128 MaintenanceConfigUpdateResponseCompactionTargetSizeMB = "128"`

  - `SnapshotExpiration MaintenanceConfigUpdateResponseSnapshotExpiration`

    Configures snapshot expiration settings.

    - `MaxSnapshotAge string`

      Specifies the maximum age for snapshots. The system deletes snapshots older than this age.
      Format: <number><unit> where unit is d (days), h (hours), m (minutes), or s (seconds).
      Examples: "7d" (7 days), "48h" (48 hours), "2880m" (2,880 minutes).
