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 be updated so that customers can utilize the faster add and remove shard machinery that Replication is building in PM-2322 MotivationThe current data migration when adding or removing a shard, chunk migration, is too slow. Customers are greatly disappointed with the current migration speeds they experience today. With an updated balancer that can leverage the faster data migration machinery customers will be able to move 1TB of data to/from a shard in a day or less which now takes nearly a month (without concurrency).
