------------------------------------
Hi Matthias,
I've started working on this and wanted to confirm my understanding.
The addtional parameter for auto-reset will need to be the same for all calls
to {{KStreamBuilder.stream}} and {{KStreamBuilder.table}} for a given single
instance of {{KStreamBuilder}}, but can differ for separate instances.
For example given two {{KStreamBuilder}} instances {{kb1}} and {{kb2}} you
could do the following:
{{kb1.stream("foo", "earliest")}}
{{kb1.stream("bar", "earliest")}}
{{kb2.stream("baz", "latest")}}
{{kb2.table("bar", "latest")}}
but not this:
{{kb1.stream("foo", "latest")}}
{{kb1.stream("bar", "earliest")}}
as this second case above would reguire multiple consumers in the underlying
{{StreamThread}} of the {{KafkaStreams}} instance obtained from using {{kb1}}
as a construction parameter
Is this correct?

> 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.
