Gopal V commented on HIVE-9730:
-------------------------------
That is true, the initialize won't be sped up at all.
Instead, what you propose would prevent any un-necessary Appender code from
appearing in the JIT tracing & the JIT will remove all logging as dead-code
instead.
> LLAP: make sure logging is never called when not needed
