This release of the Workload Manager service introduces the following new features:
File Size Reports
File size reports are now available in Workload Manager. File size reporting helps you identify data that is stored inefficiently, in small files or partitions. If a query is running slowly or your Impala cluster crashed, you can look at file size metadata in Workload Manager to determine if a large number of files or partitions is causing the problem.
The Workload Manager navigation menu has been updated to organize information based on engine type. In the Engines menu, you can select an engine type to view the dashboard for that engine, which includes all the usual widgets, such as Trend, Queries, Resource Consumption, and Workloads. You can still see the Summary page for all your engines in the Summary tab at the top of the menu.
