Viraj Jasani commented on HBASE-25914:
--------------------------------------
Nice one [~GeorryHuang].
[~stack] slowLog (and eventually largeLog) was introduced as part of
HBASE-22978, the purpose is to save slow/large RPC calls in in-memory ring
buffer at RegionServer with complete logs (as opposed to truncating some
details as we do while logging through slf4j
[here|https://github.com/apache/hbase/blob/master/hbase-server/src/main/java/org/apache/hadoop/hbase/ipc/RpcServer.java#L502]).
> Provide slow/large logs on RegionServer UI
