Calling COMMIT will cause the current transaction to save itself.

A COMMIT statement ends a transaction within Drizzle and makes all changes visible to other users. The order of events is typically to issue a START TRANSACTION statement, execute one or more SQL statements, and then issue a COMMIT statement. Alternatively, a ROLLBACK statement can be issued, which undoes all the work performed since START TRANSACTION was issued. A COMMIT statement will also release any existing savepoints that may be in use.

For example, DML statements do not implicitly commit the current transaction. If a user's DML statements have been used to update some data objects, and the updates need to be permanently recorded in the database, you can use the COMMIT command.
