Latest Patents

Sang-Sheng Tung holds a patent titled "Minimum latency reinstatement of database transaction locks." This patent describes a method for transferring a transaction workload of a primary process pair. The primary pair has access to a stable storage volume for storing data items and a log for storing transaction processing updates to data items. A backup process pair is established for the primary pair, ensuring that it can take over should the primary pair fail. The method includes maintaining a lock table and writing update records to the log by the primary pair. These update records encompass any locks from the lock table related to the updates. In the event of a primary pair failure, the storage volume is locked, and the backup pair reads the log to reconstruct the lock table. Once the locks are reconstructed, the lock on the storage volume is released, allowing the backup pair to process the workload.
