New in version 3.4.
Disables the autosplit flag in the
config.settingscollection. When auto-splitting is enabled for a sharded cluster, MongoDB automatically splits chunks based on the shard key values the chunk represents to keep the chunks from growing too large.
Auto-splitting is enabled by default. For more information on chunk splits, see Chunk Splits.Note
Starting in MongoDB 4.2,
sh.stopBalancer()also disables auto-splitting for the sharded cluster.
