db.collection.dataSize()¶

db.collection.dataSize()¶

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 size field returned by the collStats command.

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

Returns:	The size in bytes of the collection. `Data compression` does not affect this value.

This method provides a wrapper around the size output of the collStats (i.e. db.collection.stats()) command.
