REAL-TIME TRANSACTION SCHEDULING IN A DISTRIBUTED DATABASE

摘要

In one exemplary embodiment, a method of a distributed database system includes the step of receiving a database transaction with a node of the distributed database system. A priority of the database transaction is determined. A load of a transaction queue of the node is determined. The execution of a database transaction is delayed if the load of the transaction queue is greater than a first-water mark. The database transaction is delayed for a specified period. A portion of the database transaction is execution after the specified period. It is determined if the load of the queue is below a second-water mark after the specified period. A remaining portion of the database transaction can be processed if the load of the queue is below the second-water mark.
