Investigate changes in SERVER-75082: Make balancer migrations throttling configurable

XMLWordPrintableJSON

      Original Downstream Change Summary

      WE introduced a new server parameter "balancerMigrationsThrottlingMs" on the config server that allows to throttle balancing operation.

      description: The minimum amount of time between two consecutive balancing rounds

      Sleep between balancer rounds in the case where the last round found some chunks which needed to be balanced. This value should be set sufficiently low so that imbalanced clusters will quickly reach balanced state, but setting it too low may cause CRUD operations to start failing due to not being able to establish a stable shard version.

      Description of Linked Ticket

      Make the following parameters configurable:

      Balancer Migrations Throttling
      Currently the minimum time between migrations is hardcoded to 1 sec. The new configurable parameter will be defaulted to 1 sec as well.
