The patent application (Publication Number: US20240028596A1) describes a computer-implemented method for maintaining data in a data management system. The method involves storing a set of documents in a log-structured object store with sequence numbers and values, utilizing log segments, log-structured merge-trees for mapping keys to sequence numbers, and a delete list for managing stale document sequence numbers. The system monitors fragmentation within log segments and triggers compaction operations when fragmentation exceeds a set threshold. Additionally, the method includes handling client queries, searching for keys in cache memory and log-structured merge-trees, obtaining document values, and updating documents efficiently.

Furthermore, the patent application details the steps for maintaining data in a data management system using a computer-readable storage medium and a computer system. These steps involve storing documents, managing merge-trees and delete lists, monitoring fragmentation, and initiating compaction operations. The system also handles client queries, retrieves document values, and updates documents effectively. By utilizing log-structured object stores, merge-trees, and delete lists, the method ensures efficient data management and retrieval processes. Overall, the patent application outlines a comprehensive approach to data maintenance in a system that prioritizes performance and scalability through innovative techniques such as log compaction and query optimization.
