We are currently using an ignite setup with caches with very large offheap sizes (10GB+) and in these caches we are inserting entries of roughly 30 kB. We flush the entries to disk every minute using write-behind.
What we observe is that after a while, the inserts of new entries into the cache seem to become synchronized with the writing of entries to disk. Considering our disk is much slower than writing in memory, this is effectively throttling our inserts. We noticed that the WriteBehindTotalCriticalOverflowCount in the metrics is pretty high as well, which leads us to believe that inserts are waiting for entries to be written to disk. Is this correct, and if so, how can we increase the write-behind backlog? -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Inserts-stalled-by-write-behind-process-tp3390.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
