Latest Patents

One of his latest patents is titled "Compaction of documents in a high density data storage system." This innovative system utilizes a hybrid key-value storage engine that incorporates a log-structured merge tree and a segmented log-structured object store. The system is designed to perform garbage collection of stale document versions, thereby avoiding index lookup during log segment compaction. It effectively separates index and document data to minimize write amplification. Additionally, the system maintains a delete list using a log-structured merge-tree to store stale document sequence numbers and corresponding sizes per log segment. For each log segment, the system assesses fragmentation based on the sizes of deleted documents. If the fragmentation exceeds a predetermined threshold, the system initiates a compaction operation for that log segment.

Another significant patent by Rigby is "High density data storage based on log structured storage techniques." Similar to his previous work, this system also employs a hybrid key-value storage engine and focuses on optimizing data storage through effective garbage collection and fragmentation management.
