![]() For this multitenant architecture by department, ExampleCorp can achieve read/write isolation using the Amazon Redshift data sharing feature and meet its unpredictable compute scaling requirements using concurrency scaling. ExampleCorp would like to manage resources and priorities on Amazon Redshift using WLM queues. The service-level performance requirements vary by the nature of the workload and user personas accessing the datasets. They have variety of workloads with users from various departments and personas. Use case overviewĮxampleCorp is an enterprise using Amazon Redshift to modernize its data platform and analytics. We also show how to assign user roles to WLM queues and how to use WLM query insights to optimize configuration. We guide you through common WLM patterns and how they can be associated with your data warehouse configurations. This post provides examples of analytics workloads for an enterprise, and shares common challenges and ways to mitigate those challenges using WLM. ![]() We have introduced support for Redshift roles in WLM queues, you will now find User roles along with User groups and Query groups as query routing mechanism. You can use RBAC to control end-user access to data at a broad or granular level based on their job role. Role-based access control (RBAC) is a new enhancement that helps you simplify the management of security privileges in Amazon Redshift. When users belonging to a user group or role run queries in the database, their queries are routed to a queue as depicted in the following flowchart. WLM queues are configured based on Redshift user groups, user roles, or query groups. In Amazon Redshift, you implement WLM to define the number of query queues that are available and how queries are routed to those queues for processing. Each workload type has different resource needs and different service-level agreements (SLAs).Īmazon Redshift workload management (WLM) helps you maximize query throughput and get consistent performance for the most demanding analytics workloads by optimally using the resources of your existing data warehouse. We also see more and more data science and machine learning (ML) workloads. With Amazon Redshift, you can run a complex mix of workloads on your data warehouse, such as frequent data loads running alongside business-critical dashboard queries and complex transformation jobs.
