Cache Interface Garbage Collection for Heap Memory Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing memory management systems face inefficiencies in optimizing heap memory usage, particularly in cache implementations, leading to suboptimal performance and increased memory overhead.
Innovation Solution
The solution involves extending a cache implementation with a base class and attaching a utility instance to it, registering the cache with a garbage collector routine, and triggering garbage collection cycles to clean caches when a threshold is exceeded, based on defined space constraints.

1Speed
If cache implementations store more data to improve performance, then future requests can be served faster, but heap memory usage increases leading to memory overhead
Solution Approach 1:
The garbage collector routine monitors heap memory usage and provides feedback by triggering cache cleaning operations when thresholds are exceeded. The system continuously monitors memory occupancy and dynamically adjusts cache behavior based on current heap conditions, creating a closed-loop control system that balances performance and memory usage.
Solution Approach 2:
The system changes the operational parameters of caches dynamically by adjusting the cleaning threshold and space constraint values based on heap memory conditions. When memory usage exceeds thresholds, the garbage collector modifies cache behavior parameters to clean more aggressively, thereby adapting the system's memory consumption characteristics to current conditions.
2Productivity
If cache implementations allocate more memory to store data, then more data can be cached for faster access, but system memory overhead increases
Solution Approach 1:
The cache system integrates self-service memory management by incorporating garbage collector functionality directly into the cache implementation through the base class. The cache automatically monitors its own memory usage and triggers cleaning operations when necessary, eliminating the need for external memory management intervention and enabling autonomous optimization of memory allocation.
Solution Approach 2:
The invention merges the garbage collector functionality with the cache implementation by extending the cache base class with garbage collection capabilities. This integration combines two previously separate functions (caching and memory management) into a unified system that handles both data storage and memory optimization together, reducing overall system overhead.
3Ease of manufacture
If existing memory management systems are used without extensions, then implementation is simpler, but heap memory optimization is inefficient
Solution Approach 1:
The base class extension provides universal memory management functionality that can be applied to multiple cache implementations simultaneously. By implementing garbage collection capabilities in the base class, the system creates a multi-functional component that handles both standard cache operations and advanced memory optimization, making the enhanced functionality widely applicable across different cache types without requiring separate implementations.
Data Source
AI summary
The use of heap memory is optimized by extending a cache implementation with a CacheInterface base class. An instance of a ReferenceToCache is attached to the CacheInterface base class. The cache implementation is registered to a garbage collector application. The registration is stored as a reference list in a memory. In response to an unsatisfied cache allocation request, a garbage collection cycle is triggered to check heap occupancy. In response to exceeding a threshold value, the reference list is traversed for caches to be cleaned based upon a defined space constraint value. The caches are cleaned in accordance with the defined space constraint value.
