- abortTransaction
- New in version 4.0. - Terminates the multi-document transaction and rolls back any data changes made by the operations within the transaction. That is, the transaction ends without saving any of the changes made by the operations in the transaction. - Tip- In the - mongoShell, this command can also be run through the- Session.abortTransaction()helper method.- Helper methods are convenient for - mongousers, but they may not return the same level of information as database commands. In cases where the convenience is not needed or the additional return fields are required, use the database command.- To run the - abortTransaction, the command must be run against the- admindatabase and run within a- Session().- The command has the following syntax: - { - abortTransaction: 1, - txnNumber: <long>, - writeConcern: <document>, - autocommit: false, - comment: <any> - } 
Behavior
Atomicity
When a transaction aborts, all data changes made by the writes in the transaction are discarded without ever becoming visible and the transaction ends.
Security
If running with auditing, operations in an aborted transaction are still audited.
