[jira] [Commented] (KAFKA-4628) Support KTable/GlobalKTable Joins

    [ https://issues.apache.org/jira/browse/KAFKA-4628?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17224330#comment-17224330 ] 

Hartmut Armbruster commented on KAFKA-4628:
-------------------------------------------

Hi, has the content of KIP-314 been reviewed yet?

Are the concerns <quote>'for relational data with a very narrow domain'</quote> - which have been outlined in great detail by [~abellemare] - still valid with the final solution/implementation of KIP-213 / KAFKA-3705 ?

> In KIP-99 we have added support for GlobalKTables, however we don't currently support KTable/GlobalKTable joins as they require materializing a state store for the join.
