I read the cluster how-to regarding. I'm still not clear on a couple of
details if is just using DeltaManager and SimpleTcpCluster:
1. If useDirtyFlag is false, I assume that the session is entire
replicated after each and every access. Is this correct?
2. If useDirtyFlag is true, are only the pieces of the session that
were changed (via setAttribute(), removeAttribute(), etc) sent
throughout the cluster?
* Or is this a separately configurable option? If so, when
one calls setAttribute() and/or removeAttribute multiple
times on the same attribute during the same request, are the
duplicate events/deltas coalesced?
I'm just trying to understand the behavior and capabilities of the
clustering a bit better. I naively expected to find replication only
when setAttribute(), removeAttribute() or the like are called /and/ that
these changes would be coalesced into a minimalistic delta that would
then be pushed to other nodes in the cluster (with a separate timestamp
on each attribute if necessary).
