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().

The method takes the following arguments:

Parameter Type Description
namespace string The namespace (i.e. <database>.<collection>) of the sharded collection that contains the chunk to split.
query document 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 } )
