Users can continue to use the 1.9 versions of the 0.8/0.9 connectors
with future versions of Flink.
We just make it official that we no longer actively develop them,

Hi all,
Sorry for being late on this thread. My hunch is that 0.8 and 0.9 is old
enough to deprecate. However, after checking the downloads statistics from
Apache, I am not completely sure anymore.
Here are some Kafka broker jar download stats from the past month according
to Apache Nexus[1]. Since Flink only supports Scala 2.11, I only listed
Scala 2.11 here.
Scala 2.11:
version downloads percentage
0.8.2.1 215478 27.01%
2.0.1 155984 19.55%
1.1.0 85794 10.75%
1.0.1 53745 6.74%
0.9.0.1 39825 4.99%
And out of all Scala versions in the broker downloads, Scala 2.11 accounts
about 75% of the total downloads. From all the numbers I can see, it looks
there are about 1/4 of the users still using Kafka 0.8. I have to admit it
is also quite counter intuitive for me. I am pretty sure that new users are
not going to use Kafka 0.8 anymore, but the existing users are moving
slowly.
However, these stats may not necessarily prevent us from dropping connector
support for Kafka 0.8 and 0.9, if we assume the users are not going to
upgrade their Flink version, which might be the case given they did not
upgrade their Kafka versions for long either.
To avoid surprises, I'd still prefer following the proper deprecation
process. i.e. mark the connectors as deprecated, announce the deprecation
plan in the release note, and remove them 1-2 releases later if we don't
hear complaints from the users.
Thanks,
Jiangjie (Becket) Qin

Hi Chesnay,
+1 for dropping. I have not heard from any user using 0.8 or 0.9
for
a
long
while.
Cheers,

Hello,
What's everyone's take on dropping the Kafka 0.8/0.9 connectors
from
the
Flink codebase?
We haven't touched either of them for the 1.10 release, and it
seems
quite unlikely that we will do so in the future.
We could finally close a number of test stability tickets that
have
been
lingering for quite a while.
Regards,
Chesnay
