abortTransaction

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 mongosh, this command can also be run through the Session.abortTransaction() helper method.

Helper methods are convenient for mongosh users, 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 admin database and run within a Session().

Compatibility

This command is available in deployments hosted in the following environments:

MongoDB Atlas: The fully managed service for MongoDB deployments in the cloud

Note

This command is supported in all MongoDB Atlas clusters. For information on all commands, see Unsupported Commands.

MongoDB Enterprise: The subscription-based, self-managed version of MongoDB
MongoDB Community: The source-available, free-to-use, and self-managed version of MongoDB

Syntax

The command has the following syntax:

db.adminCommand(
   {
     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.
