Abstract

See full text

A method and system for data recovery in a parallel database system in which data stored in the database has been corrupted by a transaction or operation. Transaction log files corresponding to each node of the parallel database are scanned to determine an operation that caused the corruption of the stored data. Information corresponding to the corrupted data before the operation causing the corruption is then generated based on the scanned transaction log. The operation responsible for corrupting the data is then rolled back, and the corrupted data is replaced with the original data stored in the database prior to the corruption.
