Hi, I am trying to understand few things:
in a normal consumer-process-produce topology, consumer is polling records, then process each and then gives to producer to produce on destination topic. In this case, is the 'produce' a synchronous call i.e does it happen in the same consumer thread or produce takes place in a background producer thread asynchronously? If asynchronous, then how can consumer commit offset before produce happened successfully? If synchronous, then consumer thread gets held till produce happens, possibly increasing consumer lag?
