摘要： 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.

摘要翻译： 并行数据库系统中数据恢复的方法和系统，其中存储在数据库中的数据已被事务或操作破坏。 对与并行数据库的每个节点相对应的事务日志文件进行扫描，以确定导致存储数据损坏的操作。 然后根据扫描的事务日志生成与导致破坏的操作之前的损坏的数据相对应的信息。 然后，负责破坏数据的操作被回滚，并且损坏的数据将被替换为在损坏之前存储在数据库中的原始数据。
