Description
Starting from v6.0, the balancer is distributing data based on the data size on shards and not merely on the number of chunks. Because of that, it is totally useless to presplit the session collection during balancing rounds and it's also counterproductive because (1) chunks will not be moved and (2) starting from v7.0 the auto merger will squash them back together.
