-------------------------------------

Thanks [~dwysakowicz]  for the reply.
Sorry for the inaccurate description of this jira.
I  am not sure the max capacity of the cache  in some extreme cases. But it encountered the HEAP OOM in my CEP job, which contains great many NodeId & EventId & sharedBufferEdge objects in the hproof file.
