Motivation

Kafka Brokers today rely on Apache Zookeeper. Many folks in the community have expressed a desire to either change the zkclient and start using Apache Curator or allowing other systems like etcd, consul, Apache Cassandra and others to handle the role Zookeeper is currently playing. By allowing the brokers to have both a way to plug-in another server for storing the meta data and also for leader election then we can have the ability to-do this.

Public Interfaces

Proposed Changes

Compatibility, Deprecation, and Migration Plan

• What impact (if any) will there be on existing users?
• If we are changing behavior how will we phase out the older behavior?
• If we need special migration tools, describe them here.
• When will we remove the existing behavior?

Rejected Alternatives

If there are alternative ways of accomplishing the same thing, what were they? The purpose of this section is to motivate why the design is the way it is and not some other way.
