STORAGE TRANSACTIONS

摘要

A system that includes a plurality of nodes configured to execute storage transactions. The nodes include a first node and a plurality of other nodes. The storage transactions are grouped into transaction sets that are to be executed in a predetermined order that ensures that dependencies between the transactions are observed. A cluster sequencer that resides on the first node is configured to increment a sequence number that identifies an active transaction set of the transaction sets and send the sequence number from the first node to the plurality of other nodes. Upon receipt of the sequence number, each one of the plurality of other nodes begins executing the transactions of the active transaction set without waiting for confirmation that all of the plurality of other nodes have the same sequence number.
