Hi John,
thanks for the update. It could be helpful if you can share your exact
use case (I will reproduce and investigate).
Regards
JB

Hello,
We've been trying to scale Cellar horizontally, but as we bring up more
nodes, there is a lot of network synchronization between all the nodes to
the point bringing up multiple nodes at the same time takes many minutes. I
have not yet been able to perform root cause analysis but my hunch at this
point is the synchronization mechanism, where the push/pull of nodes w/i a
Cellar group seems to cause a lot of network chatter in the cluster. In
looking athe code, it seems the first node of a group should push to the
data grid, subsequent nodes should pull.
The Hazelcast serialization exceptions mentioned in an earlier post (
http://karaf.922171.n3.nabble.com/Cellar-2-2-4-cellar-event-Hazelcast-serialization-exception-tp4024747.html
) may (or may not) contribute to the slow start up of the cluster.
I'll try and gather more data as well as perform root cause analysis, but
any insight would be appreciated.
Thanks,
John T.
