> The current simple assignor doesn't offer perfect sharing between share
> consumers of a share group. Hence, I came up with the following steps -
> # depending on the no. of members and subscribed topic partitions (whether
> they are greater, equal or lesser), we need to come up with a hard limit on
> maximum and minimum no. of assignments for each members. There can also be a
> range that we can come up with regarding no. of assignment of topic
> partitions. There should also be a range of no. of members assigned to a
> topic partition.
> # have a rebalancing as the fourth step in the assignment where we make sure
> that point 1 is followed. This can be a random assignment for the first few
> iterations but depending on those iteration results, we can have a concrete
> assignment by moving partitions from one member to another.
