GetTableAutoScalingSettings
Returns auto scaling related settings of the specified table in JSON format. If the table is a multi-Region table, the Amazon Region specific auto scaling settings of the table are included.
Amazon Keyspaces auto scaling helps you provision throughput capacity for variable workloads efficiently by increasing and decreasing your table's read and write capacity automatically in response to application traffic. For more information, see Managing throughput capacity automatically with Amazon Keyspaces auto scaling in the Amazon Keyspaces Developer Guide.
