describe_global_table

DynamoDB.Client.describe_global_table(**kwargs)

Returns information about the specified global table.

Warning

This documentation is for version 2017.11.29 (Legacy) of global tables, which should be avoided for new global tables. Customers should use Global Tables version 2019.11.21 (Current) when possible, because it provides greater flexibility, higher efficiency, and consumes less write capacity than 2017.11.29 (Legacy).

To determine which version you’re using, see Determining the global table version you are using. To update existing global tables from version 2017.11.29 (Legacy) to version 2019.11.21 (Current), see Upgrading global tables.

Response Structure

• (dict) –

  • GlobalTableDescription (dict) –

    Contains the details of the global table.

    • ReplicationGroup (list) –

      The Regions where the global table has replicas.

      • (dict) –

        Contains the details of the replica.

        • RegionName (string) –

          The name of the Region.

        • ReplicaStatus (string) –

          The current state of the replica:

          • ACTIVE - The replica is ready for use.

          • REGION_DISABLED - The replica is inaccessible because the Amazon Web Services Region has been disabled.

          Note

          If the Amazon Web Services Region remains inaccessible for more than 20 hours, DynamoDB will remove this replica from the replication group. The replica will not be deleted and replication will stop from and to this region.
