Guozhang, Matthias, Thanks for the comments. I have updated the KIP, (JIRA title and description as well).
I had thought about introducing a separate interface altogether, but extending the current one makes more sense. As for intermediate callbacks based on time or number of records, I think the latest update to the KIP addresses this point of querying for intermediate results, but it would be per batch restored.
