             Summary: SQL: Metrics of using memory quotas.
                 Key: IGNITE-12020
                 URL: https://issues.apache.org/jira/browse/IGNITE-12020
             Project: Ignite
          Issue Type: New Feature
          Components: sql
            Reporter: Pavel Kuznetsov

Only local (per node) metrics are in scope.

Metrics to implement:
1) How many times memory quota have been requested on the node by all the queries in total. (org.apache.ignite.internal.processors.query.h2.QueryMemoryManager)
2) How much memory all the queries are allowed to reserve on this node in total. (Possibly constant value until node reboot)
3) How much memory currently available for the queries on this node.
