        • enabled (boolean) –

          Whether table optimization is enabled.

        • vpcConfiguration (dict) –

          A TableOptimizerVpcConfiguration object representing the VPC configuration for a table optimizer.

          This configuration is necessary to perform optimization on tables that are in a customer VPC.

          Note

          This is a Tagged Union structure. Only one of the following top level keys will be set: glueConnectionName. If a client receives an unknown member it will set SDK_UNKNOWN_MEMBER as the top level key, which maps to the name or tag of the unknown member. The structure of SDK_UNKNOWN_MEMBER is as follows:

          'SDK_UNKNOWN_MEMBER': {'name': 'UnknownMemberName'}

          • glueConnectionName (string) –

            The name of the Glue connection used for the VPC for the table optimizer.

            • snapshotRetentionPeriodInDays (integer) –

              The number of days to retain the Iceberg snapshots. If an input is not provided, the corresponding Iceberg table configuration field will be used or if not present, the default value 5 will be used.

            • numberOfSnapshotsToRetain (integer) –

              The number of Iceberg snapshots to retain within the retention period. If an input is not provided, the corresponding Iceberg table configuration field will be used or if not present, the default value 1 will be used.

            • cleanExpiredFiles (boolean) –

              If set to false, snapshots are only deleted from table metadata, and the underlying data and metadata files are not deleted.

          The configuration for an orphan file deletion optimizer.

          • icebergConfiguration (dict) –

            • orphanFileRetentionPeriodInDays (integer) –

              The number of days that orphan files should be retained before file deletion. If an input is not provided, the default value 3 will be used.

            • location (string) –

              Specifies a directory in which to look for files (defaults to the table’s location). You may choose a sub-directory rather than the top-level table location.
