Re: [DISCUSS] KIP-842: Add richer group offset reset mechanisms

[Matthias J. Sax]

Thanks for the KIP.

I don't think I fully digested the proposal yet, but my first reaction 
is: this is quite complicated. Frankly, I am worried about complexity 
and usability.

Especially the option `safe_latest` is a "weird" one IMHO, and `nearest` 
is even more complex.

The problem at hand (as I understand it from the Jira) is a real one, 
but I am wondering if it would be something that should be addressed by 
the application? If you pass in strategy `none`, and a new partition is 
added, you can react to it by custom code. For regular startup you can 
still go with "latest" to avoid reprocessing the history.

Adding "latest/earliest_on_start" seems useful, as it seems to also 
address https://issues.apache.org/jira/browse/KAFKA-3370
