Answer: Turn on concurrency scaling at the workload management (WLM) queue level in the Redshift cluster.
Concurrency scaling in Amazon Redshift allows you to support thousands of concurrent users and queries. To use it, you enable concurrency scaling at the WLM queue level. You cannot turn it on during cluster creation globally or set it for the daily usage quota directly as a switch. Redshift Serverless scales automatically and does not use traditional WLM queues for concurrency scaling.
