Original Downstream Change Summary Planning on making changes to the balancer so additional documentation will be needed Description of Linked TicketEpic Summary SummaryThe balancer will have a new policy that will distribute all collections equally across the shards in a cluster by data size. MotivationToday only sharded collections are balanced across shards which can lead to a poor distribution of the data across the shards which leads to less than optimal resource utilization at a cluster level. Customers desire their workload to be as evenly distributed across the shards in their cluster as possible. To better distribute the workload across the cluster the balancer will take into account the size of both sharded and unsharded collection and will be able distribute unsharded and sharded collections as needed to achieve the goal of equal distribution of data across all shards.
