MongoDB has been granted a patent for a database system that allows for multi-document transactions. The system includes a database with multiple data storage nodes and can perform operations on multiple documents within a transaction. If an error occurs during the transaction, the system can reverse the operations using a transaction identifier.

Database system for performing multi-document transactions
A recently granted patent (Publication Number: US11768885B2) describes a database system that includes a database with at least one data storage node and a processor that executes various system components. The system components consist of an interface component, a transaction processing component, and a transaction identification component.
The interface component is responsible for receiving a multi-document transaction, which includes a first operation to modify data in a first document and a second operation to modify data in a second document. The first and second documents are stored in the database, and the modifications made by these operations establish a relationship between the data in the two documents.
The transaction processing component performs the multi-document transaction on the database by executing the first operation on the first document. It then determines whether any errors occurred during the transaction. If an error is detected, the component uses a transaction identifier to reverse the first operation performed on the first document.
The system also includes a transaction identification component that generates the transaction identifier and associates it with the multi-document transaction. This allows the transaction processing component to link the first and second operations with the transaction identifier.
In addition, the patent describes a configuration where multiple processors are involved in the execution of the system components. One processor handles the transaction identification component, while another processor executes the transaction processing component. The transaction identification component transmits the first and second operations, along with the transaction identifier, to the second processor.
The transaction processing component can perform parts of the multi-document transaction by executing the first and second operations on a primary data storage node. It also triggers secondary data storage nodes to replicate these operations.
The patent further explains that the transaction processing component associates the first and second operations with the transaction identifier by storing a relationship between each operation and the identifier. This allows the component to reverse the first operation by identifying it through the stored relationship.
The database system described in the patent follows an eventual consistency model. It includes a primary data storage node with an operation log and secondary data storage nodes that retrieve and replicate operations from the log. The transaction processing component writes parts of the first and second operations to the operation log during the multi-document transaction.
If no errors occur during the transaction, the transaction processing component outputs a confirmation and may proceed to perform the second operation on the second document.
Overall, this patent presents a database system that enables the execution of multi-document transactions and provides mechanisms for error detection and reversal of operations.
