Hi Denis, We are using CacheMetrics.getKeySize api to get size of a cache. Does this api give cache size of entire cache or just the size of the partitions local to the node?

I tried to run a cluster with a cache configured like you described, but everything works fine. Could you provide more information about this issue? A project with a reproducer will be ideal. Are you sure that you measure size correctly? Denis ср, 22 нояб. 2017 г. в 1:28, Biren Shah <[email protected]<mailto:[email protected]>>: Hi, We have a cluster of 4 nodes. On start of the cluster we load our caches. In of our cache we are load around 2 million entries. We also monitor cache size at regular interval. The behavior we are noticing is that after initial load the cache size seems to be correct for few mins. But then the size changes and it indicates that there are only 1 million entries in the cache. Meaning initially cache size is ~2 million and within few minutes it changes to ~1 million. We are deleting anything from the cache. Do entries get off loaded to off-heap? Cluster node are setup to have 8GB memory and 8 cores. Configuration for the cache in question is: CacheConfiguration<String, Entry> cacheConfig = new CacheConfiguration<>(); cacheConfig.setOnheapCacheEnabled(true); cacheConfig.setCacheMode(CacheMode.PARTITIONED); cacheConfig.setBackups(1); cacheConfig.setCopyOnRead(false); cacheConfig.setWriteSynchronizationMode(CacheWriteSynchronizationMode.FULL_SYNC); cacheConfig.setStatisticsEnabled(true); -Biren
