Stamatis Zampetakis commented on HIVE-27751:
--------------------------------------------
Thanks for working on this ticket [~rameshkumar]. Can you please address the
questions/comments below?
It's a bit unclear what the query compilation summary will contain and how it
is displayed. Please enrich the description of this JIRA ticket with some
sample output from the new logs.
The HS2 logs already contain measurements from the compilation phase when the
debug mode is enabled. Is the new summary redundant with respect to that or
does it contain new information as well?
The JIRA summary mentions that logs are somehow "accumulated" but it is unclear
to what accumulation refers to? Are we accumulating compilation times from
multiple queries? What exactly do we accumulate?
