[jboss-jira] [JBoss JIRA] Reopened: (JGRP-931) Logical addresses: canonicalize UUIDs with IDs (shorts)

Logical addresses: canonicalize UUIDs with IDs (shorts) ------------------------------------------------------- Key: JGRP-931 URL: https://issues.jboss.org/browse/JGRP-931 Project: JGroups Issue Type: Feature Request Reporter: Bela Ban Assignee: Bela Ban Fix For: 3.x Instead of using UUIDs as addresses, the cluster members should agree on shorts, e.g. 1 for A, 2 for B and so on, and use these instead of UUIDs. This happens after a certain warmup time. E.g. the coord could assign these IDs, so they're unique. IdAddress and UUID have to be able to do equals() or compareTo() with each other ! Advantage: - we send a short (2 bytes) instead of a UUID (16 bytes) - we use an IdAddress (class with a short) instead of a UUID. This is 6 bytes less per instance - IdAddress might be faster with equals() and hashCode() than UUID
