Abstract

A system and method of performing snapshot isolation in distributed databases. Each node stores local snapshot information that enforces snapshot isolation for that node. The method includes partially processing a distributed transaction by a first node, receiving a global commit identifier from a coordinator, and continuing to process the distributed transaction, by the first node and a second node, in accordance with the global commit identifier.
