sh.removeTagRange()

Definition

sh.removeTagRange(namespace, minimum, maximum)

Note

This method aliases to sh.removeRangeFromZone(). MongoDB provides Zone sharding as the successor to tag-aware sharding.

Removes a specified shard tag from a defined range of shard key values. sh.removeTagRange() takes the following arguments:

Parameter	Type	Description
namespace	string	The namespace of the sharded collection to tag.
minimum	document	The minimum value of the shard key from the tag. Specify the minimum value in the form of <fieldname>:<value>. This value must be of the same BSON type or types as the shard key.
maximum	document	The maximum value of the shard key range from the tag. Specify the maximum value in the form of <fieldname>:<value>. This value must be of the same BSON type or types as the shard key.

Use sh.removeTagRange() to ensure that unused or out of date ranges are removed and hence chunks are balanced as required.

Only run sh.removeTagRange() when connected to a mongos instance.

Compatibility

This method is available in deployments hosted in the following environments:

• MongoDB Atlas: The fully managed service for MongoDB deployments in the cloud

• MongoDB Enterprise: The subscription-based, self-managed version of MongoDB

• MongoDB Community: The source-available, free-to-use, and self-managed version of MongoDB

Example

Given a shard key of {state: 1, zip: 1}, the following operation removes an existing tag range covering zip codes in New York State:

sh.removeTagRange( "exampledb.collection",
                { state: "NY", zip: MinKey },
                { state: "NY", zip: MaxKey }
              )
