HI ilya - Thanx for the reply. What you said is exactly what's happening I guess. We do see this warning that pages will be rotated from disk and the write process will slow down.
Here is the message that we see in the logs: WARN ][data-streamer-stripe-22-#59][PageMemoryImpl] Page replacements started, pages will be rotated with disk, this will affect storage performance (consider increasing DataRegionConfiguration#setMaxSize). We do have inline indexes on the SQL tables, that's also probably causing some of this I guess. Is there any solution other than increasing the off heap size ??
