This is the first diff for the implementation of JoinGroup logic for static membership. The goal of this diff contains: * Add group.instance.id to be unique identifier for consumer instances, provided by end user; Modify group coordinator to accept JoinGroupRequest with/without static membership, refactor the logic for readability and code reusability. * Add client side support for incorporating static membership changes, including new config for group.instance.id, apply stream thread client id by default, and new join group exception handling. * Increase max session timeout to 30 min for more user flexibility if they are inclined to tolerate partial unavailability than burdening rebalance. * Unit tests for each module changes, especially on the group coordinator logic. Crossing the possibilities like: 6.1 Dynamic/Static member 6.2 Known/Unknown member id 6.3 Group stable/unstable 6.4 Leader/Follower The rest of the 345 change will be broken down to 4 separate diffs: * Avoid kicking out members through rebalance.timeout, only do the kick out through session timeout. * Changes around LeaveGroup logic, including version bumping, broker logic, client logic, etc. * Admin client changes to add ability to batch remove static members * Deprecate group.initial.rebalance.delay Reviewers: Liquan Pei <liquanpei@gmail.com>, Stanislav Kozlovski <familyguyuser192@windowslive.com>, Jason Gustafson <jason@confluent.io>, Guozhang Wang <wangguoz@gmail.com> |
