Latest Patents
Lyuping Du holds a patent titled "Active invalidation of metadata cache entries." This patent describes techniques for actively invalidating cache entries. A first timestamp and a second timestamp are stored by a compute instance, with the first timestamp corresponding to the initial time the computing instance read from a version update log in a database. The second timestamp corresponds to the last time the computing instance read from the version update log. The compute instance can read records from the version update log that are associated with version timestamps greater than the second timestamp. This allows the compute instance to invalidate a first set of cache entries with older versions stored in a cache based on reading the records, while retaining a second set of cache entries. The compute instance can then execute a query using the second set of cache entries. This innovative approach enhances the efficiency of cache management in computing systems.
