László Bodor updated HIVE-27640:
--------------------------------
Description:
This is kind of hard to catch easily, but I would like to see
something/anything about query concurrency in the query counters. This way we
can instantly see in the query summary what happened. I mean counters like:
1. how many queries were running when this query arrived
2. same as 1) but in query stage level
2a) how many queries were being compiled (or waiting for compilation) when this
query started to compile (or started to enqueued for compilation)
2b) how many queries were waiting for a coordinator when this query started to
get a coordinator
2c) how many queries were in the Run DAG phase, when this query started to run
DAG
