It sounds like you either have hot partition(s) or hardware issue on
that node. I;m mentioning hardware issue because I had a server with
faulty CPU fan and the CPU on it overheats and causes frequency
throttling, the result is a single server with much higher load than the
rest of the nodes
All these symptoms indicate a potential hotspot in this replica, which can
be caused by one or likely multiple "hot" partitions. Finding out which
particular partition(s) is responsible for this is tricky, but good
candidates are the ones mentioned in the log warning.
Ideally you should fix your
Hello team,
On a given day , a node in 27 node cluster observed higher frequency of
garbage collection. Mostly young gc.
I have found below issues:
1. Higher number of slow queries being observed on that particular node for
that particular day compared to other days
2. Higher outgoing traffic
