Title: Weinan Wang: Innovator in Database Technology
Introduction
Weinan Wang is a prominent inventor based in Bellevue, WA (US), known for his contributions to database technology. With a total of 6 patents, he has made significant advancements in the field, particularly in enhancing distributed database systems.
Latest Patents
One of his latest patents focuses on increasing distributed database capacity. This invention discloses various embodiments for adding new nodes to a distributed database while minimizing downtime. The database is partitioned among multiple nodes in a cluster, with each node storing a respective portion of the database. Portions of the database are replicated to corresponding physical standbys, ensuring data integrity and availability. For each portion, a first portion is mapped to an existing node, while a remaining portion is mapped to a physical standby. The cluster is then updated to include these physical standbys as additional nodes among which the database is partitioned.
Another notable patent by Weinan Wang facilitates data redistribution in database sharding. This invention describes a method for maintaining a horizontally partitioned database into a set of first buckets using modulo-based assignments. A fixed number of these first buckets are stored in multiple physical data stores. The database is then repartitioned into a set of second buckets, ensuring that the data remains unmoved between the physical data stores during the repartitioning process.
