sh.splitFind(namespace, query)

Splits the chunk that contains the shard key value specified by the query at the chunk's median point. sh.splitFind() creates two roughly equal chunks. To split a chunk at a specific point instead, see sh.splitAt().


mongo Shell Method

This page documents a mongo method. This is not the documentation for database commands or language-specific drivers, such as Node.js. To use the database command, see the split command.

For MongoDB API drivers, refer to the language-specific MongoDB driver documentation.

The method takes the following arguments:

The namespace (i.e. <database>.<collection>) of the sharded collection that contains the chunk to split.
A query document that specifies the shard key value that determines the chunk to split.

The sh.splitFind() method wraps the split command.

In most circumstances, you should leave chunk splitting to the automated processes within MongoDB.

To use sh.splitFind(), the sharded collection must be populated.

For the sharded collection, the following example splits, at the median point, a chunk that contains the shard key value x: 70.

sh.splitFind( "", { x: 70 } )
