db.collection.storageSize()¶ mongoShell MethodThis page documents the
mongoshell method, and does not refer to the MongoDB Node.js driver (or any other driver) method. For corresponding MongoDB driver API, refer to your specific MongoDB driver documentation instead.Returns: The total amount of storage 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 bydb.collection.dataSize().Provides a wrapper around the
storageSizefield of thecollStats(i.e.db.collection.stats()) output.Starting in MongoDB 4.4, to run on a replica set member,
collStatsoperations require the member to be inPRIMARYorSECONDARYstate. If the member is in another state, such asSTARTUP2, the operation errors.In previous versions, the operations can also be run when the member is in
STARTUP2. However, the operations wait until the member transitions toRECOVERING.
