退役brokers

The partition reassignment tool does not have the ability to automatically generate a reassignment plan for decommissioning brokers yet. As such, the admin has to come up with a reassignment plan to move the replica for all partitions hosted on the broker to be decommissioned, to the rest of the brokers. This can be relatively tedious as the reassignment needs to ensure that all the replicas are not moved from the decommissioned broker to only one other broker. To make this process effortless, we plan to add tooling support for decommissioning brokers in the future.

分区重新分配工具没有自动生成退役broker的重新分配规则的能力。因此，管理员要有一个重新分配计划，迁移broker上所有要停运的副本到其余的broker上。这会比较繁琐，因为重新分配要确保所有的副本从退役的broker迁移到另一个没有停运的broker。为了使这个过程更轻松，我们计划在未来增加退役broker的工具支持。
