James Clarke commented on KAFKA-3370:
-------------------------------------
I think those options make sense. Without these options it is hard to get
mirror maker to work correctly (without risk of duplicate data) for regex
whitelist and newly created topics (KAFKA-3848).
> Add options to auto.offset.reset to reset offsets upon initialization only
> --------------------------------------------------------------------------

> Key: KAFKA-3370
> URL: https://issues.apache.org/jira/browse/KAFKA-3370
> Project: Kafka
> Issue Type: Bug
> Reporter: Guozhang Wang
> Assignee: Vahid Hashemian
> Fix For: 0.10.1.0
>
>
> Currently "auto.offset.reset" is applied in the following two cases:
> 1) upon starting the consumer for the first time (hence no committed offsets
> before);
> 2) upon fetching offsets out-of-range.
> For scenarios where case 2) needs to be avoid (i.e. people need to be
> notified upon offsets out-of-range rather than silently offset reset),
> "auto.offset.reset" need to be set to "none". However for case 1) setting
> "auto.offset.reset" to "none" will cause NoOffsetForPartitionException upon
> polling. And in this case, seekToBeginning/seekToEnd is mistakenly applied
> trying to set the offset at initialization, which are actually designed for
> during the life time of the consumer (in rebalance callback, for example).
> The fix proposal is to add two more options to "auto.offset.reset",
> "earliest-on-start", and "latest-on-start", whose semantics are "earliest"
> and "latest" for case 1) only, and "none" for case 2).
