[jira] [Commented] (IGNITE-3227) IgniteCache: add method to calculate size per partition

["Alexey Goncharuk (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IGNITE-3227?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15360787#comment-15360787 ] 

Alexey Goncharuk commented on IGNITE-3227:
------------------------------------------

 - No need to have two separate tasks for partition size. It is enough to have Long size task and cast long to int (with a proper range check and exceprion, if needed) in CacheProxy
 - Because of above, no need for int-size methods on IgniteInternalCache interface
 - No need to send the task to all nodes in the cluster. Method should map partition to nodes and send the task only to responsible nodes.
 - We should reserve partition and only count size of partitions in OWNING state.

> 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}
