[jboss-jira] [JBoss JIRA] Commented: (JGRP-1315) Discovery: don't send view back with discovery response

[Bela Ban (JIRA)]

    [ https://issues.jboss.org/browse/JGRP-1315?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12620252#comment-12620252 ] 

Bela Ban commented on JGRP-1315:
--------------------------------

For discovery requests triggered by GMS (JOIN), every member returns:
- UUID
- Logical name
- Physical address

For discovery requests triggered by MERGE2, every member returns:
- *ViewId* (instead of View)

For merge-triggered discovery requests, MERGE2 only checks if ViewIds differ. If they do, a merge is initiated.

--> We do not need to send the entire Views, which saves space on large clusters

> We send back a View with each discovery response. This is wasteful if we have large clusters.
> SOLUTION: change this to only return the coordinator's address for initial discovery.
> Note: look into only returning the ViewId for merge triggered discovery
