Latest Patents

Fei Qiu holds a patent for a technique titled "Two phase move of database tables." This invention presents a two-phase move technique for relocating groups of tables, which may reduce cross-host communication and the duration of table locks. The method involves moving a group that includes a first table and a second table to a destination host system. It is accomplished by creating a third table that replicates the first table and a fourth table that replicates the second table on the destination host, along with replicas of other tables in the group. Notably, the tables in the group are not locked against modifications during the creation of the replica tables. After the replicas are created, the roles of the original tables and the newly created tables are switched, allowing for a seamless transition. The original tables are then dropped after the role switching is complete.
