Abstract:
Systems and methods are directed for detecting and resolving write-write conflicts among a plurality of transactions received from master nodes (100-1, 100-2 … 100-N) of a multi-writer database system (200). The method includes receiving a plurality of REDO logs and storing the plurality of REDO logs in a buffer, each REDO log associated with the one of the plurality of transactions, selecting one REDO log of the plurality of REDO logs; persisting the transaction associated with the one REDO log in a local storage when a write-write conflict is detected between the one REDO log and at least one other REDO log of the plurality of REDO logs prior to committing the transaction associated with the one REDO log; and transmitting a status of the transaction associated with the one REDO log to a global transaction manager (GTM) (302).
