Cody Koeninger commented on SPARK-17812:
----------------------------------------
Assign is useful, otherwise you have no way of consuming only particular
partitions of a topic.
Yeah, I just ended up using jackson tree model directly, as you said the
catalyst stuff isn't really applicable.
Branch with initial implementation is is at
https://github.com/koeninger/spark-1/tree/SPARK-17812 , will send a PR once I
have some tests... trying to figure out if there's a reasonable way of unit
testing offset out of range, but may just give up on that if it seems flaky.
