Hi again,
I've found that each node will keep its own state data separate from each of
the other nodes with no replication or communication when only storing state
data in memory.

Subject: In-memory TridentState distribution
Date: Wed, 25 Mar 2015 12:00:09 -0400
Hi all,
I am using Trident state without any external persistent storage (like
Memcached or Cassandra) and I was wondering how this state is kept consistent
across nodes in a cluster (if at all). Would the same in-memory state object be
replicated across all nodes? Or would the state object be distributed across
all nodes as if they shared a pool of memory just for the state object?
Thanks,John
