Graham McIntire	571814c080	Remove Redis dependency from RateLimiterWrapper ... - Always use ETS-based RateLimiter instead of checking for REDIS_URL - Remove RedisRateLimiter calls that were causing crashes - Simplify wrapper to only delegate to Aprsme.RateLimiter	2025-10-25 09:44:44 -05:00
Graham McIntire	226a53bf61	Add Redis-based distributed caching and rate limiting ... This commit introduces a dual-mode caching and rate limiting system that can use either Redis (for distributed deployments) or ETS/Cachex (for single-node setups). Key changes: - Add Cache abstraction layer that automatically switches between Redis and Cachex - Implement RedisCache module with full distributed cache functionality - Implement RedisRateLimiter with sliding window algorithm for accurate rate limiting - Add RateLimiterWrapper to provide unified API for both implementations - Update application startup to conditionally use Redis when REDIS_URL is set - Migrate all cache operations to use the new Cache abstraction - Support graceful fallback to ETS-based solutions when Redis is unavailable The system automatically detects Redis availability via REDIS_URL environment variable and switches between implementations without code changes. This enables proper distributed caching and rate limiting in Kubernetes deployments while maintaining backward compatibility for development environments. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>	2025-07-26 15:29:38 -05:00
