Vaibhav Gumashta commented on HIVE-4617:
----------------------------------------
Just for comparison, metastore currently has 200 min and 100,000 max threads.
Proposing here, that HS2 has 500 thrift workers and 500 async threads. Also,
was thinking of changing the async thread pool to a cached thread pool, which
will not keep all 500 threads alive all the time, but will create new threads
when required, keeping the unused ones alive for a certain time before purging
them. Will be interesting to hear more thoughts. Thanks!
