Abstract

A two copy versioning scheme is proposed. The scheme provides efficient implementation for a high read load database and eliminates read dependencies. The versioning scheme provides efficient implementation for transactions executing under ANSI READ COMMITTED isolation, and is extensible to serializable isolation. The two-copy versioning scheme is garbage free meaning that all versions of data records are used during execution and is adapted to index scanning operations. A 'deferred delete' scheme allows read transactions to complete data deallocation operations. Statements that require 'snapshots' are efficiently supported.
