Subject Problem about cache data size
Date Wed, 18 May 2016 08:59:38 GMT
I am trying to estimate cache data size when setting CacheMode.PARTITIONED
with different replications.
I confirmed the cache data size by ignitevisorcmd and found the result is a
bit strange.
Following is my cache configures.
CacheCfg.setCacheMode(CacheMode.PARTITIONED);
CacheCfg.setMemoryMode(CacheMemoryMode.OFFHEAP_TIERED);
CacheCfg.setOffHeapMaxMemory(0);
CacheCfg.setSwapEnabled(false);

case 1 : CacheCfg.setBackups(0);
Non-heap memory initialized 23m
Non-heap memory used 58m
Non-heap memory committed 88m
Non-heap memory maximum 130m

case 2 : CacheCfg.setBackups(1);
Non-heap memory initialized 23m
Non-heap memory used 58m
Non-heap memory committed 88m
Non-heap memory maximum 130m

case 3 : CacheCfg.setBackups(2);
Non-heap memory initialized 23m
Non-heap memory used 58m
Non-heap memory committed 88m
Non-heap memory maximum 130m

I have 2 questions:
1. How to estimate the memory used for the cache data? 
According to "initialized ", "used", "committed" or "maximum"?
2. Why memory used looks same in different replications?
