Transaction Scope: Topic -> KStream -> KTable

Architecture and Design
1

Hey! Sorry, I don’t know if this is the correct category.

It has been suggested that a transactional producer performing topic partition send can wrap the streaming to a consumer that transforms and writes to a KTable:

producer.beginTransaction();
producer.send(record);
// in-txn-scope: post topic partition write streamed record
// in-txn-scope: streamed record transformed and written to ktable
producer.commitTransaction();

Is this true or false?

Thanks a bunch!

Shall I take no response as a “no” answer? It seems obvious to me that the KStream and/or KTable are not in the Producer’s potential multi-partition 2PC. Still, I did want to inquire in case there was recent support for KTable transactional consistency.
