[jboss-jira] [JBoss JIRA] (JGRP-2230) Multiple discovery protocols without MULTI_PING

[Radoslav Husar (JIRA)]

    [ https://issues.jboss.org/browse/JGRP-2230?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13522801#comment-13522801 ] 

Radoslav Husar commented on JGRP-2230:
--------------------------------------

It should be possible to introduce a new API already in 4.x that protocols themselves can already (i.e. optionally) implement so they can be ready for 5.x when the time comes without code changes.

> Currently, {{MULTI_PING}} is needed to forward discovery requests to multiple discovery protocols. If we change the API in 5.0, and pass a {{Responses}} object down to the discovery protocols, and each discovery protocol forwards discovery requests down (and responses up), and they all add responses to the same {{Responses}} object, then we would not need {{MULTI_PING}} any longer.
> However, this is an API change, so can be done only in 5.0.
