How to find the fhe size of the specific Document in MonogoDB Collection?

问题

I have 100k documents in an MonoDB Collection, the document({id : '789736363828292'}) has 20k Documents/Records. I would like find the memory utilized by that particular document.

Please help me to find the memory size in MB in MongoDB console.

You can use Object.bsonsize in MongoShell which will return a BSON size (in bytes) of one document. Try

Object.bsonsize(db.col.findOne({id : '789736363828292'}))
