[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:comment-tabpanel&focusedCommentId=12977180#comment-12977180 ] 

Dennis Reed commented on ISPN-4291:
-----------------------------------

In addition, this step currently blocks writes to the cache until it completes.

As you stated on the support list discussion:  "I think it should be ok to remove data from the cache store afterwards, without blocking writes."

> 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.
