Transactional cache invalidation for inter-node caching

Abstract:

Disclosed herein are system, method, and computer program product embodiments for efficiently providing transaction-consistent snapshots of data stored in or associated with a database stored within a database management system. An embodiment operates by receiving, at a source database, an update request to update a table at the source database and transmitting a message to a cache node to invalidate a copy of a table time stamp associated with the table, where the copy of the table time stamp is stored at the cache node. The embodiment continues by updating the table at the source database based on the update request.
