Marton Elek commented on HDDS-3354:
-----------------------------------
bq. One of the main reason is as bucket cache is full table cache it will be in
memory, we need some JVM tunings to be set, because, without tuning, we are
seeing a lot of GC Pauses happening in OM.
That's very interesting. Do you have more finding about the root cause? How
many buckets did you have? It's very surprising to have GC pause for a few
thousands of buckets especially as they are not frequently updated. Do we need
to adjust something on the cache size?
