Action-based routing of a transaction in an online transaction processing system

摘要

A request to perform a transaction on a database in an online transaction processing system is accessed by a node. The sets of data in the database that the transaction is to act on are determined. The transaction is then separated into actions according to the data dependencies of the actions; an action is established for each set of data that is acted on by the transaction. The actions are communicated to the nodes that store the data that the respective actions depend on. The actions are then performed on the nodes to which they were routed.
