Maximum documents in one mongodb collection

Question

What will be the maximum number of documents we can store in one mongodb collection? I have one million documents with around 100 fields to insert into one collection. So, is it good to use one collection or should I go for multiple collections?

Answer 1

Unless you create a capped collection, there is no limit to the number of documents in a collection.

There is a 16MB limit to the size of a document (use gridfs in this situation) and limits in the storage engine for the size of the database and data.

If your documents do not exceed 16MB, then having 1 million of them will not be problematic for the mongodb storage engine limits.

Answer 2

Yes. You can store more than a billion. The better your server hardware, the better the MongoDB performance.
