> 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
