At KAFKA-2984: ktable sends old values when required <https://github.com/apache/kafka/pull/672#issue-122101101>, @ymatsuda writes:
> NOTE: This is meant to be used by aggregation. But, if there is a use case like a SQL database trigger, we can add a new KTable method to expose this. Looking through the source it does not seem that this API was ever exposed. Not finding anything on Google on this subject either. The SQL database trigger is my exact use case. Enabling change-streaming for some tables would help simplify my code. Is this possible? Is this scheduled for a future version? Thank you, Dmitry
