Arjun Satish commented on KAFKA-7877:
-------------------------------------
[~Andrew Bourgeois]: updated the KIP. Also, added a section to "rejected
alternatives" that indicate that we didn't address putting records that fail
while writing to put() in a sink connectors.
> Connect DLQ not used in SinkTask put()
