Node Storage Relocation Based on Update Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Microblog platforms, the frequent forwarding and commenting on popular messages lead to a high frequency of node loading and relocation between memory and file, causing performance issues due to the limited memory space and resulting in a vicious cycle that reduces server performance.
Innovation Solution
A method that involves receiving a write operation request and storing nodes in memory with an update time, periodically scanning nodes to determine which ones to relocate to a file based on their update time, and optimizing the number of nodes relocated to manage memory usage efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If nodes are frequently loaded to memory to improve access speed, then node retrieval performance is improved, but the frequency of node relocation increases causing server performance to deteriorate
Solution Approach 1:
The patent changes the parameter of node storage location based on access frequency. Nodes are dynamically moved between memory and file storage according to their access patterns, allowing frequently accessed nodes to remain in memory for fast retrieval while less frequently accessed nodes are stored in files to reduce relocation frequency and maintain server performance.
2Productivity
If memory space is used to store frequently accessed nodes, then node access efficiency is improved, but the number of nodes that can be stored is limited causing more nodes to be relocated to file
Solution Approach 1:
The patent segments node storage into two locations: memory for frequently accessed nodes and file storage for less frequently accessed nodes. This segmentation allows the system to maintain a manageable number of nodes in memory for efficient access while storing additional nodes in files, effectively increasing the total quantity of stored nodes without overwhelming memory capacity.
3Quantity of substance
If nodes are relocated from memory to file to reduce memory pressure, then memory usage is optimized, but the frequency of loading nodes back to memory increases creating a vicious cycle
Solution Approach 1:
The patent implements a feedback mechanism that monitors node access patterns and dynamically adjusts node placement between memory and file storage. By continuously observing which nodes are accessed frequently and which are not, the system can make informed decisions about where to store nodes, reducing unnecessary relocations and breaking the vicious cycle of frequent loading and relocation.
