Subject [jira] [Commented] (KAFKA-6275) Extend consumer offset reset tool to support deletion
Date Mon, 27 Nov 2017 19:14:00 GMT

    [ https://issues.apache.org/jira/browse/KAFKA-6275?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16267288#comment-16267288

Jason Gustafson commented on KAFKA-6275:
----------------------------------------

[~vahid] Sure, makes sense to get in KIP-175 first (I'll try to ping a couple committers for
one more vote). Removing the retention time field is probably the way we want to go so maybe
an explicit flag would be better. It might even be better to have a separate DeleteOffsets
API.

> It's useful to have a way to delete the offsets of a consumer group explicitly. The reset
tool already supports a number of different ways to alter stored offsets, so perhaps we could
add a {{--clear}} option. Note that this would require a change to the OffsetCommit protocol
which does not currently support deletion. Perhaps if you commit an offset with a retention
time of 0, we can treat it as a deletion.
