Transmission Format Cache for Database Read Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern database systems face inefficiencies in processing data stored in formats optimized for storage, as they need to be reformatted for transmission to clients, which can lead to performance issues due to the need to collect attributes from different storage areas and handle various data formats, especially when accessed through interfaces like APIs or RESTful services.
Innovation Solution
Implementing a transmission format cache in database nodes that converts data items from storage format to transmission format, enabling efficient data retrieval by caching formatted data items and using APIs to manage cache entries, thereby optimizing read operations and adapting to performance requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If data is stored in optimized storage format with attributes grouped in different areas, then storage efficiency is improved, but data retrieval and reformatting complexity increases
Solution Approach 1:
The patent pre-formats data items into transmission format and stores them in a cache structure alongside the storage format data. This preliminary action of creating transmission format copies in advance eliminates the need for complex reformatting operations during data retrieval, as the formatted data is already prepared and readily available for immediate transmission to clients.
Solution Approach 2:
The patent introduces a transmission format cache as an intermediary layer between the storage format data and the client transmission process. This cache stores pre-formatted data items and serves as a mediator that provides directly usable transmission format data without requiring complex real-time reformatting operations, thereby simplifying the data retrieval process while maintaining storage efficiency.
2Manufacturing precision
If data reformatting is performed for each access request, then data transmission accuracy is improved, but processing time increases
Solution Approach 1:
The patent performs the data reformatting operation in advance and stores the formatted data in a cache. By preparing the transmission format data beforehand, the system eliminates the need to perform time-consuming reformatting operations during each access request, thereby significantly reducing processing time while ensuring data transmission accuracy through the use of pre-validated formatted data.
Solution Approach 2:
The patent creates copy versions of data items in transmission format and stores them in the cache alongside the original storage format data. These copies are generated once and reused for multiple access requests, eliminating the need to repeatedly perform reformatting operations. This copying approach maintains data transmission accuracy while dramatically reducing the processing time required for each subsequent data retrieval operation.
3Productivity
If transmission format cache is implemented, then data retrieval performance is improved, but memory usage increases
Solution Approach 1:
The patent implements a transmission format cache that stores pre-formatted data items in memory, creating a localized high-performance storage area for frequently accessed data. This local quality approach provides fast data retrieval performance for the cached data while allowing the system to maintain standard storage formats for less frequently accessed data, thereby optimizing the balance between retrieval performance and memory usage.
Solution Approach 2:
The patent applies partial action by caching only the transmission format versions of data items that are frequently accessed, rather than formatting and caching all data. This selective caching approach improves data retrieval performance for the most critical data while limiting memory usage by avoiding the storage of transmission format copies for all data items in the database.
Data Source
AI summary
A transmission format cache may be implemented at a database storage node. Versions of data items stored in a database at the database storage node may be processed according to anticipated access requests to generate an anticipated access responses. The anticipated access responses are then stored in a transmission format cache to provide low latency reads of the data items. The versions of the data items may be processed as a result of updates to the database items. The database storage node may be one of a plurality of database storage nodes implementing a distributed database system with the transmission format cache implementing a portion of a distributed response cache providing low latency, eventually consistent or consistent reads of data items in a distributed database.
