ASF GitHub Bot commented on DRILL-6348: --------------------------------------- Github user sachouche commented on the issue: https://github.com/apache/drill/pull/1237 @vrozov, your observation is valid, we need more JIRAs to fix the reporting problem **Current Fix** - At this time, the UnorderedReceiver didn't account for any consumed memory - This fix, taxes the operator only when it consumes buffers **Potential Enhancements** Solution I - Create a new fragment child Allocator which will own the received (not yet consumed) batches - Improve the UI to report this allocator size - This solution is simple and complementary to the current work Solution II - Have the receiver operator drain the batch queue - Essentially, the receiver will have a private queue from where to consume batches - I personally don't like this solution as it prevents us from improving the Drill network protocol - Draining the batches for the sake of reporting will make it harder for the network layer to prefetch batches in an optimal manner; the queue size should be an indicator on how many pending batches there are. > Unordered Receiver does not report its memory usage > --------------------------------------------------- > > Key: DRILL-6348 > URL: https://issues.apache.org/jira/browse/DRILL-6348 > Project: Apache Drill > Issue Type: Task > Components: Execution - Flow > Reporter: salim achouche > Assignee: salim achouche > Priority: Major > Fix For: 1.14.0 > > > The Drill Profile functionality doesn't show any memory usage for the > Unordered Receiver operator. This is problematic when analyzing OOM > conditions since we cannot account for all of a query memory usage. This Jira > is to fix memory reporting for the Unordered Receiver operator. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
