Abstract
Techniques for information update involve: updating, at a first node, first information in a first memory and second information associated with the first information, wherein the first information needs to be persistently stored, and the second information can be obtained from the first information and does not need to be stored persistently; storing the updated first information and the updated second information into a first region and a second region of a first persistent storage device, respectively; synchronizing the updated first information and the updated second information to a second node; and validating the updated first information stored in the first region and invalidating the updated second information stored in the second region based on a determination that the synchronization is successful. Such techniques can achieve incremental update of non-persistent information, thereby improving system performance.
