Cody Koeninger commented on SPARK-17815:
----------------------------------------

My personal concerns about complexity are because I'm the one who answers 
nearly every email on the spark user list regarding the Kafka integration.

My business need relative to this ticket is that any Kafka integration I use 
must give me a way to transactionally store offsets and results.  If those 
downstream offsets aren't used as at least a source of truth, then that goal 
isn't met.  If this ticket is implicitly saying WAL is the only source of 
truth, that's a problem for me.

SIP is what it is or may not be, we're where we are now having the discussion 
we're having now, and I'll leave it at that ;)

> Since we manage our own offsets, we have turned off auto-commit.  However, 
> this means that external tools are not able to report on how far behind a 
> given streaming job is.  When the user manually gives us a group.id, we 
> should report back to it.
