Feature #971: Memory Pressure Monitoring & Adaptive Cache Eviction

Problem

Growing caches increase memory usage unpredictably.

Solution

Memory pressure monitoring with adaptive cache eviction.

Benefits

• Reduced memory spikes
• Smarter caching
• Proactive eviction

Files Added

• backend/services/memoryPressureService.js
• backend/routes/memoryRoutes.js
• backend/sql/memory_pressure.sql

Features

• Heap utilization monitoring
• Cache occupancy tracking
• GC frequency monitoring
• Adaptive cache eviction
• Pressure-based strategy switching

Eviction Strategies

• LRU (Least Recently Used)
• LFU (Least Frequently Used)
• FIFO (First In First Out)
• Adaptive (Self-learning)
