# Redis Cost Optimization Expert ## Cost Factors | Factor | Impact | Optimization | |--------|--------|--------------| | Memory | Primary cost | Compression, TTLs | | Connections | Resource usage | Pooling | | Commands | CPU usage | Batching, pipelines | | Network | Egress | Compression | ## Audit Workflow ### Step 1: Check Memory Usage ```bash redis-cli INFO memory ``` Analyze fragmentation, peak memory, and eviction stats. See `cases/memory-optimization.md` for optimization. ### Step 2: Monitor Connections ```bash redis-cli INFO clients ``` Check connection count and timeout settings. See `cases/connection-optimization.md` for pooling strategies. ### Step 3: Identify Hot Keys ```bash redis-cli --hotkeys ``` Find keys with disproportionate access patterns. See `cases/hot-key-optimization.md` for sharding strategies. ### Step 4: Analyze Slow Commands ```bash redis-cli SLOWLOG GET 10 ``` Identify expensive operations and optimize queries. ## Matching Cases | Problem | Case File | Solution | |---------|-----------|----------| | High memory | `cases/memory-optimization.md` | TTLs, compression | | Connection issues | `cases/connection-optimization.md` | Pooling | | Hot keys | `cases/hot-key-optimization.md` | Sharding | ## Benchmark Reference | Optimization | Before | After | Improvement | |--------------|--------|-------|-------------| | Memory compression | 1GB | 300MB | 70% | | Connection pooling | 500 conns | 50 conns | 90% | | Key sharding | 100K ops/key | 10K ops/key | 90% | ## Output Format ``` ## Redis Cost Audit Report ### 1. Current Usage - Memory: X MB / X MB (X%) - Connections: X / X (X%) - Commands/sec: X - Hit rate: X% ### 2. Performance Issues - Slow commands: X - Hot keys: X - Memory fragmentation: X ### 3. Recommendations (by priority) 1. [P0] Apply case: <case-name> → Expected improvement: XX% ### 4. Cost Projection - Current: $X/month - After optimization: $X/month - Savings: $X/month (XX%) ```
