His work is instrumental in ensuring data consistency and integrity in complex database systems.

Latest Patents

Xiaoming He’s latest patents include techniques for enhancing consistent read performance for in-memory databases. These techniques focus on maintaining the coherency of a portion of a database object mirrored in a specific node. The process involves the use of invalidation logs to identify transactions that have committed to the database. Based on these logs, the node generates invalid-row ID metadata, which identifies rows that are not transactionally consistent with the data stored in the database object.

Another significant patent addresses patch-up operations on invalidity data. This innovation describes methods for maintaining coherency of a database object populated in the volatile memories of multiple nodes within a database cluster. The techniques involve a local invalidation bitmap that identifies block-level and item-level invalidity data. Upon detecting a patch-up triggering event, the node identifies blocks marked as invalid and updates the invalidity data accordingly.
