For Dart-only workloads, it is not possible for merge buffers to be exhausted, because the number of concurrent queries is capped at the number of merge buffers by DartWorkerMemoryManagementModule. However, When native and Dart queries are run on the same Historical, it is possible for buffers to be held by native queries. In this case, Dart workers must wait for buffers to become available. This waiting now happens in the worker runner thread, and lasts for the configured query timeout. At this time, the waiting is not interrupted when a cancellation request arrives from the controller. This should be addressed in another patch. -- This is an automated message from the Apache Git Service.
