metadataCacheMode property

String? metadataCacheMode
getter/setter pair

Metadata Cache Mode for the table.

Set this to enable caching of metadata from external data source.

Optional. Possible string values are:

  • "METADATA_CACHE_MODE_UNSPECIFIED" : Unspecified metadata cache mode.
  • "AUTOMATIC" : Set this mode to trigger automatic background refresh of metadata cache from the external source. Queries will use the latest available cache version within the table's maxStaleness interval.
  • "MANUAL" : Set this mode to enable triggering manual refresh of the metadata cache from external source. Queries will use the latest manually triggered cache version within the table's maxStaleness interval.
