> TubeMQ uses the server-side rebalance mode to allocate tasks. At present, the
> task allocation mode is relatively single, and the implementation of this
> part is relatively hard-coded, and the readability and maintainability are
> not good enough.
> Existing solutions take all the partitions of the topic set subscribed by the
> consumer group according to the number of consumers in the consumer group,
> and then extract the partitions at consumer number interval, and allocate the
> partitions to the corresponding client; if the client or partition has
> increasing or decreasing, the client with more partitions subscriptions will
> release the partitions through partial balance, and will be allocated the
> released partitions to consumers with less or no subscription partitions for
> balanced consumption.
> If you are interested, you can try to abstract this piece. At the same time,
> you can also propose your rebalance plan, which is compatible on the basis of
> existing rebalance.
