sh.removeTagRange(namespace, minimum, maximum, tag)¶

New in version 3.0.

Removes a range of shard key values to a shard tag created using the sh.removeShardTag() method. 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.
`tag`	string	The name of the tag attached to the range specified by the `minimum` and `maximum` arguments to.

Use sh.removeShardTag() to ensure that unused or out of date ranges are removed and hence chunks are balanced as required.

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

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 },
                "NY"
              )
