Subject [jira] [Commented] (KAFKA-5087) Kafka Connect's configuration topics should always be compacted
Date Wed, 19 Apr 2017 16:48:42 GMT

    [ https://issues.apache.org/jira/browse/KAFKA-5087?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15975066#comment-15975066

Ewen Cheslack-Postava commented on KAFKA-5087:
----------------------------------------------

I think this is really part of the general "create internal topics automatically" issue that
is already filed in KAFKA-4667. Going to close this as duplicate, but copy over some of the
notes since compaction wasn't mentioned in that JIRA yet.

> New users frequently lose their connector configuration because they did not manually
set the topic deletion policy to "compact". Not a good first experience with our system.
> 1. If the topics do not exist, Kafka Connect should create them with the correct configuration.
> 2. If the topics do exist, Kafka Connect should check their deletion policy and refuse
to start if it isn't "compact"
> I'd love to do it (or have someone else do it) the moment the AdminClient is merged and
to have it in 0.11.0.0.
