Distributed System Data Incompatibility Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In distributed computing systems, rolling upgrades often lead to incompatibilities between different versions of data, causing disruptions and downtime, especially when multiple members operate on shared data with varying configurations and formats.
Innovation Solution
The method employs group/member dependent keys, links, and data transformation functions to manage incompatibilities by ensuring each member or group accesses the correct version of data, using techniques like member-dependent keys, group-dependent links, and data transformation functions to maintain seamless access during upgrades.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rolling upgrade is performed in a distributed system, then availability of the application is maintained and downtime is minimized, but data incompatibilities arise between different software versions operating concurrently
Solution Approach 1:
The patent segments the data access mechanism by introducing version-specific keys and links. Different members accessing the same shared data use different keys (e.g., key1 for version 1, key2 for version 2) or different links pointing to the same physical data location. This segmentation allows concurrent access to the same data by different software versions without conflict, resolving the incompatibility issue while maintaining system availability.
2Adaptability or versatility
If different members operate on shared data with varying configurations and formats, then each member can run its specific software version, but incompatibilities cause disruptions and downtime
Solution Approach 1:
The patent introduces an intermediary layer consisting of version-specific keys and links that mediate between different software versions and the shared data. The key management system acts as a mediator that translates access requests from different versions into appropriate data access operations, preventing direct conflicts and ensuring system continuity while allowing version flexibility.
3Adaptability or versatility
If data format and organizational structure changes are made for new software versions, then the new version can operate correctly, but old version members can no longer access the shared data
Solution Approach 1:
The patent adds a version dimension to the data access mechanism. Instead of having a single data format, the system maintains multiple version-specific data representations accessible through versioned keys and links. This dimensional approach allows the system to evolve data formats for new versions while preserving access paths for old versions, enabling concurrent operation across different software versions without productivity loss.
Data Source
AI summary
A method and mechanism for managing data to resolve incompatibilities between different versions of data is disclosed. According to one approach, incompatibilities to private data is managed using group/member dependent key(s)/link(s), static shared data is managed using group/member dependent key(s)/link(s), and dynamic shared data is managed using data transformation function(s).
