MongoDB Query Language (MQL) Data Size Operators
$binarysize
The `$binarySize` operator is used to return the size of a binary data field. This can be useful when dealing with binary data stored, such as images, files, or any other binary content.
$bsonsize
The `$bsonSize` operator is used to return the size of a document in bytes when encoded as BSON. It's useful for understanding the storage requirements of documents within your collections.
