Matthias J. Sax commented on KAFKA-8388:
----------------------------------------

Just to clarify: this ticket is not about Interactive Queries feature, but 
rather you want to create a derive KTable for a specific point in time or time 
range?

This sounds a little bit adding a TTL? (cf KAFKA-4212 and KAFKA-4273)

> Add methods to query for entries in KTable using timestamp

> 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.
