Reduce memory used by data structures ------------------------------------- Key: JGRP-1394 URL: https://issues.jboss.org/browse/JGRP-1394 Project: JGroups Issue Type: Enhancement Reporter: Bela Ban Assignee: Bela Ban Some protocols maintain data structures, usually one per cluster member. For example, NAKACK has a hashmap of members and their associated NakreceiverWindows. Each NRW has a RetransmitTable and a Retransmitter. Another example is STABLE. Look at those data structures and try to reduce their memory footprint. This may not be important for small clusters, but becomes important in large clusters. E.g if we have 1000 cluster nodes, then every data structure's memory footprint is multiplied by 1000 !
