CONCURRENT PROCESSING OF TRANSACTIONS AND READ OPERATIONS ACHIEVING SERIALIZATION AND ISOLATION IN CLUSTERED FILE SYSTEMS

摘要

Systems. Methods, and Computer Program Products are provided for concurrent processing of transactions and read operations for achieving serialization and isolation in a clustered file system (CFS). Users, performing read only operations, are allowed to currently access the CFS while mutually excluding and serializing transactions of users affecting a same portion of the CFS. Transactions are ordered across a cluster of nodes of the CFS according to the transactions termination time
