Rajesh Balamohan commented on HIVE-23277:
-----------------------------------------
This is to avoid JSON serialization being in the hotpath of compiler thread. In
short queries, where subsecond latency matters, this becomes an issue along
with the query complexity. BTW, its \{getExplainPlan(plan, conf, hookContext)}
also needs to be moved out of the in-thread processing.
> HiveProtoLogger should carry out JSON conversion in its own thread
