I have followed http://apacheignite.gridgain.org/v1.5/docs/capacity-planning for capacity planning. But I have a question regarding "Add around 20MB per cache." line. Does it mean per cache entry, per node, per map?
I have inserted only 1 entry in the cluster. Following are the stats: Size of 1 entry =108KB 1 Node internal memory = 200-300MB. So we have 4 servers and 2 clients. 4 Node internal memory = 300MB*4 = 1.2GB Not sure what does "Add around 20MB per cache" means? Heap memory used across the cluster = 11745159288 = 11GB [igniteInstance.cluster().metrics() -> ClusterMetrics.getHeapMemoryUsed] I am trying to understand why the heap memory is 11GB? Finally I want to measure amount of heap memory (ONHEAP) in bytes used by this map if insert 1million entries. I was looking into igniteInstance.cache(mapName).metrics() which return CacheMetrics for that mapName. -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/How-to-get-On-heap-memory-usage-for-a-map-tp10263p10270.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
