db.collection.storageSize()

db.collection.storageSize()

Important

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 storageSize field returned by the collStats command.

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

Returns:The total amount of storage in bytes allocated to this collection for document storage.

If collection data is compressed (which is the default for WiredTiger), the storage size reflects the compressed size and may be smaller than the value returned by db.collection.dataSize()

Starting in MongoDB 4.4, to run on a replica set member, collStats operations require the member to be in PRIMARY or SECONDARY state. If the member is in another state, such as STARTUP2, the operation errors.

In previous versions, the operations also run when the member is in STARTUP2. The operations wait until the member transitioned to RECOVERING
