While I realize this only marks the old consumer as deprecated and not a
complete removal, I agree that it is somewhat premature to do this prior to
having a migration process implemented. Onur has described this in detail
in the earlier thread: http://markmail.org/message/ekv352zy7xttco5s and I'm
I cant speak for anyone else, but a rolling upgrade is definitely how we
(LinkedIn) will do the migration.

Since the APIs are super different, I expect migrating from the old to
the new consumer will involve some re-write of the app that does the
consuming. In most such cases, the upgrade path involves running both
versions side-by-side for a while, validating results and then
retiring the old version.
im all for (working towards) getting rid of old code, but there's still no
solid migration path - you'll be "stranding" users on deprecated, no longer
maintained code with no "safe" way out that does not involve downtime
(specifically old and new consumers cannot correctly divide up partitions
Very strong support from me too :)

Thanks Ismael. I added that to the KIP.

Thanks Vahid, +1 (predictably). Worth mentioning in the KIP that
compatibility with older brokers (0.10.0 and later) is another feature that
will only be supported by the Java consumer.

Hi all,
There was some discussion recently on deprecating the old consumer (
https://www.mail-archive.com/dev@kafka.apache.org/msg59084.html).
Ismael suggested to cover the discussion and voting of major deprecations
like this under a KIP.
So I started KIP-109 (
