[infinispan-issues] [JBoss JIRA] (ISPN-8402) Prevent rebalance

[Dan Berindei (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-8402?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13480700#comment-13480700 ] 

Dan Berindei commented on ISPN-8402:
------------------------------------

[~sebastian.laskawiec] this should work for the Caching Service, but it seems dangerous for the Shared Memory Service. 

Can we expose an endpoint for OpenShift to change the target number of nodes before shutting down a node and/or query the cluster if it's safe to shut down a node (and we veto the shutdown if the current number of nodes is <= target number of nodes)?

> Both Caching Service and Shared Memory Service require a way to prevent state transfer until the cluster is larger than "target" amount of nodes. 
> Note: A thing to consider during the design - we might want to have some timeout here. When we hit it, we might want to do the rebalance regardless to the number of nodes.
