The drop command removes an entire collection from a database. The command has following syntax:
{ drop: <collection_name> }
The mongo shell provides the equivalent helper method:
db.collection.drop();
Note that this command also removes any indexes associated with the dropped collection.

This command obtains a write lock on the affected database and will block other operations until it has completed.
