Andy Goldstein updated QPID-3280:
---------------------------------
Attachment: cluster_ttl.diff
Potential patch to resolve issue. Added a new "cluster clock" CPG message that
the cluster elder fires every so often (default is 10ms, but is configurable).
Each node stores and uses the cluster clock when calculating message expiration
time or determining if a message has expired. Also moved the QueueCleaner to
the cluster timer when the broker is part of a cluster.
> Message throughput suffers in a cluster when TTL set
