             Summary: Calcite engine. Reduce contention by 
QueryBlockingTaskExecutor
                 Key: IGNITE-27389
                 URL: https://issues.apache.org/jira/browse/IGNITE-27389
             Project: Ignite
          Issue Type: Improvement
            Reporter: Aleksey Plekhanov
            Assignee: Aleksey Plekhanov


Currently QueryBlockingTaskExecutor uses one lock for add task/poll task/finish 
task operations. If there are too many threads configured in pool it leads to 
contention on this lock. Let's analyze how we can reduce contention.
