Hi Saikat,
I don't think that implementation of GridCacheAdapter#localSizeLong(int
partition, CachePeekMode[] peekModes) is correct. Currently it will count all
local entries, even from other partitions.
To obtain partition size, you should use GridDhtLocalPartition#publicSize()
method. It also has methods to check whether partition is primary or backup for
a given topology version. An instance of GridDhtLocalPartition can be accessed
from GridCacheAdapter by calling {code}ctx.topology().localPartition(int p,
AffinityTopologyVersion topVer, boolean create){code}.
To count entries in swap and offheap, methods
GridCacheSwapManager#swapEntriesCount(int partId) and
GridCacheSwapManager#offheapEntriesCount(int partId) should be used,
respectively.

> IgniteCache: add method to calculate size per partition

> Labels: community, important
>
> It makes sense to add size calculation per partition. Actually the following
> methods should be added to the {{IgniteCache}} API.
> {code}
> public int size(int partition, CachePeekMode... peekModes) throws
> CacheException;
> public int localSize(int partition, CachePeekMode... peekModes);
> {code}
