Abstract:
In one embodiment, a method of performing point-in-time recovery (PITR) in a massively parallel processing (MPP) database includes receiving, by a data node from a coordinator, a PITR recovery request and reading a log record of the MPP database. The method also includes determining a type of the log record and updating a transaction table when the type of the log record is an abort transaction or a commit transaction.
