> Add methods to query for entries in KTable using timestamp

> Key: KAFKA-8388
> URL: https://issues.apache.org/jira/browse/KAFKA-8388
> Project: Kafka
> Issue Type: Improvement
> Components: streams
> Reporter: Richard Yu
> Priority: Major
> Labels: needs-kip
>
> Currently, in Kafka Streams, KTable API does not allow users to query for
> entries with a specific timestamp. The goal of this ticket is to allow a
> couple of things:
> * Retrieve entries in KTable that were inserted in the last {{K}}
> milliseconds where {{K}} could be determined by the user
> * Find key-value pairs which were put into the KTable in a specified time
> interval.
> KTable already has methods like {{filter}} and {{filterNot}}, but the
> information available to the user in these methods does not include the
> publish timestamp.
> The best way to do this is probably to add new methods which creates a new
> KTable based solely on timestamp.
