Subject [jira] [Commented] (KAFKA-5958) User StoreListener not available for global stores
Date Sun, 24 Sep 2017 23:16:01 GMT

    [ https://issues.apache.org/jira/browse/KAFKA-5958?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16178397#comment-16178397
] 

Matthias J. Sax commented on KAFKA-5958:
----------------------------------------

It should be a change in {{GlobalStateManagerImpl#restoreState}} IMHO. I think, [~bbejeck]
is already looking into this. Bill, can you assign this to yourself if you are working on
it?

> In 1.0 we added the ability to register a state restore listener, such that users can
monitor state restore progress via this callback.
> However, we no do not use this listener for global stores. Strictly speaking, global
stores are never recovered, however, at startup they are bootstrapped. We might want to consider
to user the same handler callback to allow users to monitor the bootstrapping of global stores,
too.
