Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deduplication systems face challenges in efficiently controlling the data processing rate, particularly in managing multiple dimension limits, accommodating virtual dimensions, and adapting to online changes, while maintaining independence from storage systems' layout, hardware specifications, and network conditions.
Innovation Solution
A debt/credit algorithm is employed to regulate the deduplicated data processing rate by calculating required sleep times based on maximum allowable sleep time, delta vector, and limits per time vector, allowing workers to adjust their processing according to dynamic rate limits, ensuring efficient rate control in parallel and distributed environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a rate control mechanism is implemented to regulate deduplicated data processing rate, then system efficiency and compatibility are enhanced, but processing speed may be reduced due to calculated sleep times
Solution Approach 1:
The rate control mechanism implements periodic action by calculating required sleep times for workers based on debt/credit algorithms. Workers periodically pause their processing operations according to calculated sleep intervals, which regulates the overall data processing rate while maintaining system efficiency and compatibility through controlled periodic execution rather than continuous processing
Solution Approach 2:
The system applies dynamics by making the processing rate adjustable and adaptive through the debt/credit algorithm. The calculated sleep times dynamically adjust based on current system state, allowing the processing rate to be regulated in real-time according to varying conditions while maintaining optimal performance
2Measurement precision
If multiple dimension limits are enforced for rate control, then rate regulation precision is improved, but system complexity increases
Solution Approach 1:
The system implements multiple dimension limits by extending rate control from single-dimension to multi-dimensional constraints. The debt/credit algorithm operates across multiple dimensions simultaneously, allowing precise rate regulation in complex parallel and distributed environments while managing system complexity through a unified algorithmic framework
3Adaptability or versatility
If the rate control mechanism adapts to online changes, then adaptability is improved, but processing time overhead increases
Solution Approach 1:
The rate control mechanism employs feedback by continuously monitoring system state and adjusting calculated sleep times based on current conditions. The debt/credit algorithm receives feedback from ongoing processing operations and dynamically adapts rate limits online, ensuring the system responds to changing conditions while minimizing processing time overhead through efficient feedback loops
