[JBoss JIRA] Created: (JGRP-1331) Digest: remove low seqno

Digest: remove low seqno
------------------------
Key: JGRP-1331
URL: https://issues.jboss.org/browse/JGRP-1331
Project: JGroups
Issue Type: Task
Reporter: Bela Ban
Assignee: Bela Ban
Priority: Minor
Fix For: 3.1
We don't need Digest.Entry.low_seqno for NakReceiverWindow anymore. We only need it for the Retransmitter implementations. If we can remove that last dependency, e.g. by storing the last seqno removed from a retransmitter, we can remove low_seqno from a digest. This is significant, for example if we have 100 nodes, a digest includes 300 longs:(low+highest_received+highest_delivered) * 100. If we remove low_seqno, we only have 200 longs. (These will still be further compressed in a different JIRA).
This is important for large clusters, to reduce the size of STABLE messages and views.
