> For LLAP and HS2, some configuration changes can be made to improve logging performance
> 1) LOG4j2's async logger claims to have 6-68 times better performance than synchronous
logger. https://logging.apache.org/log4j/2.x/manual/async.html
> 2) Replace File appenders with RandomAccessFileAppender that claims to be 20-200% more
performant.
> https://logging.apache.org/log4j/2.x/manual/appenders.html#RandomAccessFileAppender
> Also make async logging configurable.
