[jira] [Commented] (KAFKA-5958) User StoreListener not available for global stores

["Richard Yu (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KAFKA-5958?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16178388#comment-16178388 ] 

Richard Yu commented on KAFKA-5958:
-----------------------------------

[~mjsax] Just to clarify on a couple of things, does this only involve modification of the Stores or StoreBuilder class?
Or is there some other class (using Stores) which needs to be changed?

> 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.
