  • Description
sh.disableAutoSplit()

New in version 3.4.

Disables the autosplit flag in the config.settings collection. 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.

You can only run sh.disableAutoSplit() from a mongosh session that is connected to a mongos instance. sh.disableAutoSplit() errors if run on a mongod instance.

Note

Starting in MongoDB 4.2, sh.stopBalancer() also disables auto-splitting for the sharded cluster.
