Abstract
Disclosed herein are system, method, and computer program product embodiments for distributed transaction processing in massively parallel processing (MPP) databases. An embodiment operates by receiving a transaction including a read timestamp corresponding to a version of data of a database associated with the query. It is determined whether a locally stored portion of the data of the database has a local timestamp that is equivalent to or after the read timestamp. A lock may be requested, and if received, the data is updated.
