[VOTE] 1.1.0 RC0

[Damian Guy]

Hello Kafka users, developers and client-developers,

This is the first candidate for release of Apache Kafka 1.1.0.

This is minor version release of Apache Kakfa. It Includes 29 new KIPs. Please see the release plan for more details:

A few highlights:

* Significant Controller improvements (much faster and session expiration edge cases fixed)
* Data balancing across log directories (JBOD)
* More efficient replication when the number of partitions is large
* Dynamic Broker Configs
* Delegation tokens (KIP-48)
* Kafka Streams API improvements (KIP-205 / 210 / 220 / 224 / 239)

Hey Damian,

I think we should consider https://issues.apache.org/jira/browse/KAFKA-6593 for the release. I have a patch available, but still working on validating both the bug and the fix.

Hi Jason,

Ok - thanks. Let me know how you get on.

Cheers,

Damian

[Jason Gustafson]

The fix has been merged to 1.1.

Thanks,

Jason

[Damian Guy]

Thanks Jason. Assuming the system tests pass i'll cut RC1 tomorrow.

Thanks,

Damian

Hi, Damian,

It would also be useful to include KAFKA-6111, which prevents deleteLogDirEventNotifications path to be deleted correctly from Zookeeper. The patch should be committed later today.

Thanks,

Jun
