How to remove a document from the capped collection?

问题

When I try to remove a document in collection in MongoDB . It didn't remove because the collection is capped . My question is why? And is there a solution or other function can remove the document in this case?

回答1:

No You cannot delete documents from a capped collection. And there is no possible workaround. The only thing you can do is drop() the collection.

回答2:

You can not use remove function for capped collection. There are some restrictions on capped collections. Also you can refer this document for capped collection in mongoDB.
