UGC Message Caching Using Attribute Functions to Reduce Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current caching mechanisms for User Generated Content (UGC) messages on servers face issues such as residual old messages in cache memory and excessive storage space usage due to the need for counters to track reading frequencies, leading to inefficient use of server disk space and cache capacity.
Innovation Solution
A method and apparatus for caching UGC messages that acquire and analyze attribute information, including time and state attributes, using preset functions to determine whether messages should be cached based on a threshold of accumulated function values, eliminating the need for additional storage for reading times and optimizing cache space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional caching mechanisms use counters to track reading frequencies, then caching accuracy is improved, but storage space consumption increases due to residual old messages and excessive counter data
Solution Approach 1:
The patent extracts and removes the counter mechanism from the caching system. Instead of tracking reading frequencies with counters, the system directly evaluates messages based on their attributes (time, type, sender) using preset functions. This extraction eliminates the storage overhead of counters while maintaining caching accuracy through attribute-based evaluation.
Solution Approach 2:
The patent changes the evaluation parameters from frequency-based (counter values) to attribute-based (time, type, sender characteristics). By using preset functions that process message attributes directly, the system achieves accurate caching decisions without requiring additional storage for frequency tracking, thus resolving the contradiction between precision and storage consumption.
2Productivity
If cache memory stores more UGC messages, then cache hit rate is improved, but server disk load increases due to insufficient cache space management
Solution Approach 1:
The patent implements a dynamic caching strategy where messages are evaluated in real-time using preset functions based on their attributes. The cache dynamically adjusts which messages to store and retrieve based on current message characteristics rather than static frequency counters. This dynamic approach optimizes cache utilization, increasing hit rates while reducing unnecessary disk operations.
Solution Approach 2:
The system uses feedback from message attribute evaluation to determine caching decisions. The preset functions continuously assess incoming messages against stored messages using attribute comparison, providing feedback that guides which messages should be cached. This feedback mechanism ensures high cache hit rates while efficiently managing cache space, reducing server disk load.
3Measurement precision
If the cache evaluates multiple message attributes using complex functions, then caching accuracy is improved, but computational complexity increases
Solution Approach 1:
The patent segments the message evaluation process into distinct attribute dimensions (time attribute, type attribute, sender attribute). Each dimension is evaluated separately using dedicated preset functions, and the results are combined to make caching decisions. This segmentation reduces computational complexity by breaking down complex evaluation into manageable, independent function calls while maintaining high caching accuracy.
