Caching Sub-Query Results Across Distributed Data Stores

The patent introduces a format-independent data processing service as an intermediary layer between the distributed data stores and the query interface. This service handles format conversion and data retrieval transparently, allowing users to access data from multiple locations and formats without directly managing the complexity of data distribution. The intermediary abstracts the heterogeneity of stored data, maintaining ease of operation while supporting flexible storage architectures.

The patent implements query result caching that stores the results of sub-queries performed on distributed data. When the same or similar queries are executed, the cached results are returned directly without re-accessing the distributed data stores. This preliminary action of caching query results significantly improves query performance and productivity while maintaining the ability to store large quantities of data across distributed locations.

The patent implements a universal data processing service that handles multiple data formats, storage locations, and query types through a single standardized interface. This multi-functional service reduces system complexity by consolidating what would otherwise require multiple specialized components. The service provides format-independent access to distributed data while incorporating caching mechanisms, achieving high query performance without proportionally increasing system complexity through standardization and consolidation.
