Monitoring memory usage

The QUERY_EXECUTIONS table has all the information required to analyze a query except memory used. For memory consumption, we need to check the RESOURCE_ACQUISITIONS, which shows the memory consumed for query per node. Is there a way to view the total memory consumed by a query in the QUERY_EXECUTIONS table?

  • You could sum it up for all nodes, but I'm not sure how useful that would be. Most nodes should generally have the same memory utilization, unless you have massive data skew.
