Support throttling the balancer for sharded clusters
As high throughput clusters grow and documents become larger, the MongoDB balancer may begin impacting workloads.
I'd like the ability to throttle the speed at which the balancer or chunk migrator runs such that impact is minimised.
New in version 7.0 and also available in 6.3.1, 6.0.6, and 5.0.18 is the balancerMigrationsThrottlingMs server parameter. This new parameter allows you to specify the minimum amount of time between balancing rounds which ultimately affects the balancing rate.
