In Amazon Redshift workload management (WLM), query monitoring rules define metrics-based performance boundaries for WLM queues and specify what action to take when a query goes beyond those boundaries. The role has access to S3 and Glue, and it has been attached to the RedShift Serverless permissions. Every cluster has a default configuration that cannot be modified. ![]() WLM JSON configuration is part of the Redshift cluster parameter group. Workload Management (WLM) is an ordered set of query queues that define how resources are allocated and how queries are routed for processing. A WLM timeout applies to queries only during the query running phase.
