Latest Patents

One of his latest patents is titled "Data synchronization with minimal table lock duration in asynchronous table replication." This invention discloses a system, method, and computer program product designed to minimize table lock duration during lost change resynchronization between a source table and a replica table. The embodiment operates by detecting a restart at either a source node or a replica node. Upon detection, the source table at the source node is locked, and a database transaction is created for the lost change resynchronization operation. The source table is then unlocked, and the database transaction is compared to another based on its timestamp to determine which transaction to execute.

Another notable patent is "Log forwarding to avoid deadlocks during parallel log replay in asynchronous table replication." This invention addresses the issue of deadlocks during replication from distributed source tables to a replica node. The embodiment detects a deadlock at a parallel log replayer and selects a first replication log entry from a queue based on its potential to resolve the deadlock. The first replication log entry is forwarded to a waiting queue, allowing a second replication log entry to be replayed, followed by the first entry.
