describeTable

Returns information about the table, including the current status of the table, when it was created, the primary key schema, and any indexes on the table.

This operation only applies to Version 2019.11.21 (Current) of global tables.

If you issue a DescribeTable request immediately after a CreateTable request, DynamoDB might return a ResourceNotFoundException. This is because DescribeTable uses an eventually consistent query, and the metadata for your table might not be available at that moment. Wait for a few seconds, and then try the DescribeTable request again.
