Latest Patents

One of Yanrui Zhang's latest patents is titled "Replication of unstructured staged data between database deployments." This invention focuses on implementing unstructured data replication using either internal or external storage locations. The patent describes a method for replicating metadata, such as a directory table that lists unstructured files, across different deployments, followed by the replication of staged data. This process can be executed by replicating only the stage metadata or the database files between the deployments.

Another notable patent is "Load history calculation in internal stage replication." This invention provides techniques for deduplicating files during internal stage replication. It utilizes a directory table of the replicated internal stage, which is modified to serve as a cache for storing and retrieving original file-level metadata for the replicated files. The method prepares an initial list of candidate files for loading from the internal stage to a target deployment table, refining it through a directory table lookup. Inconsistencies between the directory table and the internal stage files prompt the target deployment to inspect user-defined file-level metadata to ensure that no duplicate files are loaded.
