Subject RE: Off-heap memory usage questions

Thank you Val.

Another question is that although the reported off-heap memory is not big (around 72M), I
observed big heap memory consumption - some as high as 6G. I am not using any expiry policy.
Is this normal?

Hi Shaomin,

1. Yes, this is a per node setting. So if there are two nodes on one box, it's possible that
20G will be allocated on this box. You should make sure that this limit correlates with the
amount of physical memory you have.
2. In 1.5. IgniteCache.metrics() return values for local node only, but you can use IgniteCache.metrics(ClusterGroup)
to get aggregated values for a set of nodes. This is already fixed in master - in 1.6 aggregated
metrics will be returned by default.
