Matthias J. Sax commented on KAFKA-4114:
----------------------------------------

Sorry for the late reply. Case #1 is already supported right now. Because there 
is a single Consumer, it's reset policy is configured via eg 
{{StreamConfig#put(ConsumerConfig.AUTO_OFFSET_RESET_CONFIG, "latest");}} which 
applies for all stream/table that are consumed. This JIRA should enable case 
#2. However, I think we do not need multiple consumers. I would rather set 
default value for this consumer config as {{"none"}} and use 
{{seekToBeginning()}} and {{seekToEnd()}} according to the provided reset 
strategy per stream/table to the manually reset the offset instead of relying 
on consumer's internal reset. WDYT? Maybe [~guozhang] also want to comment?

> Today we only have one consumer config "offset.auto.reset" to control that 
> behavior, which means all streams are read either from "earliest" or "latest".
> However, it would be useful to improve this settings to allow users have 
> finer control over different input stream. For example, with two input 
> streams, one of them always reading from offset 0 upon (re)-starting, and the 
> other reading for log end offset.
> This JIRA requires to extend {{KStreamBuilder}} API for methods 
> {{.stream(...)}} and {{.table(...)}} to add a new parameter that indicate the 
> initial offset to be used.
