Bela Ban updated JGRP-931:
--------------------------
Fix Version/s: 2.12
(was: 2.11)
Logical addresses: canonicalize UUIDs with IDs (shorts)
-------------------------------------------------------
Key: JGRP-931
URL:
https://jira.jboss.org/browse/JGRP-931
Project: JGroups
Issue Type: Feature Request
Reporter: Bela Ban
Assignee: Bela Ban
Fix For: 2.12
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
