Motivation

Today each FindCoordinatorRequest only contains a single consumer id at a time. That means if we have N number of groupIds that need to find it's coordinators, we have to send out N number of requests. This is not as efficient in some scenarios. Therefore we want to extend FindCoordinatorRequest to have multiple consumer ids.

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.
