[infinispan-issues] [JBoss JIRA] (ISPN-4291) Poor REPL state transfer performance with cache stores

[Dennis Reed (JIRA)]

     [ https://issues.jboss.org/browse/ISPN-4291?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Dennis Reed resolved ISPN-4291.
-------------------------------

    Resolution: Rejected


The entire cache store does still have to be iterated through with REPL to delete any stale data, so unfortunately this just takes a very long time with a slow cache store.

> During a state transfer every single key is loaded from the cache store to determine whether it's still owned by the local node.
> This is an extremely slow operation, and doesn't even make sense for a REPL cache.
