    摘要： Systems, methods and computer program product embodiments for providing a locking protocol for partitioned and distributed database tables are disclosed herein. A locking method includes executing, by at least one processor, a first database transaction on a second node, attempting to acquire and acquiring a lock on the second node in intentional exclusive mode, executing, by the at least one processor, a second database transaction on a first node, acquiring a lock on the first node in exclusive mode and waiting to acquire a lock on the second node in exclusive mode, routing, by the at least one processor, the first database transaction to the first node and unsuccessfully trying to acquire a lock on the first node and committing, by the at least one processor, the first database transaction.
