The drop command removes an entire collection from a database. The command has following syntax:

{ drop: <collection_name>, writeConcern: <document>, comment: <any> }

The command takes the following fields:

The name of the collection to drop.

Optional. A document expressing the write concern of the drop command. Omit to use the default write concern.

When issued on a sharded cluster, mongos converts the write concern of the drop command and its helper db.collection.drop() to "majority".


Optional. A user-provided comment to attach to this command. Once set, this comment appears alongside records of this command in the following locations:

A comment can be any valid BSON type (string, integer, object, array, etc).

New in version 4.4.

mongosh provides the equivalent helper method db.collection.drop().

Changed in version 4.2.

drop obtains an exclusive lock on the specified collection for the duration of the operation. All subsequent operations on the collection must wait until drop releases the lock.

Prior to MongoDB 4.2, drop obtained an exclusive lock on the parent database, blocking all operations on the database and all its collections until the operation completed.
