Abstract:
Disclosed herein are system, method, and computer program product embodiments for performing database processing after a lock condition. An embodiment operates by receiving a release of a lock on data of a database. It is determined whether the data was modified by a processing of a first transaction associated with the first request. The lock is provided to a second transaction associated with a second request to access the data. If the first transaction did not modify the data, a second transaction associated with the second request is retried without refreshing a snapshot of the data. If the first transaction modified the data, the snapshot of the data is refreshed before the second transaction is retried.
