This innovation provides a method for a networked and replicated database management system (DBMS) using only one-sided remote direct memory access (RDMA). Replicated databases retain some access to the stored data in the face of server failure. In the prior state of the art, after the software in the DBMS on one of the servers acted on a client's request to update the database, it would contact the other replicas of the database and ensure that they had recorded the change, before responding to the client that the transaction was complete. This innovation describes a method whereby the database client directly interacts with each DBMS replica over the network using only RDMA to directly modify the stored data while maintaining the properties of database atomicity and consistency. This method reduces transactional latency by removing any need for the server DBMS software to respond to or forward requests for service.
