Coherence Cache Prune Rate
bitcosmoMay 11 2012 — edited May 14 2012Assume cache is configured with high-unit, LRU eviction policy and default low-unit which is 75% of high-unit.
Cache prune will start when cache size reaches high-unit with LRU eviction policy until it reaches 75% of high-unit.
I know there is Coherence JMX metric named CachePrunes.
My question is how do i find out the rate of cache prune? In other word, how many entries are being prunes per second?
Assume cache is full (at max high-unit) Is it possible that the rate of creating new cache entries is faster than the rate of cache prune and cache can still overflow?
Thanks in advance.
