Non-Relational Database Query Joining via Volatile Memory Segmentation

The patent segments the storage location for joined datasets by using volatile memory as a temporary storage layer between non-volatile database indexes and the query processing system. This segmentation allows the system to retrieve data efficiently from non-volatile storage without permanently consuming non-volatile memory resources, as the joined results are held in volatile memory during processing.

Volatile memory serves as an intermediary between non-volatile database indexes and the query processing system. The joined search results are first generated and stored in this intermediate volatile memory layer, allowing efficient access during query processing while preventing direct consumption of non-volatile memory resources. This intermediary layer resolves the contradiction by providing fast access without permanent storage.

The patent applies local quality by allowing each database index to maintain its own field naming conventions and data model characteristics locally, while the joining process dynamically maps these local variations to a unified query interface. The system adapts to local field name differences at the point of joining rather than enforcing global standardization, thus reducing complexity without sacrificing adaptability.

The system dynamically changes the mapping parameters between different database indexes during the joining process. Instead of fixing field name correspondences in advance, the joining mechanism adapts parameter mappings based on the specific indexes being joined, allowing the system to handle diverse data models while maintaining a consistent query interface.
