| name | redis-audit |
| description | Redis cost optimization expert. Analyzes memory usage, connection management, command patterns, hot keys, and provides optimization strategies. Trigger when user mentions Redis costs, memory optimization, or Redis audit. |
| when_to_use | - User asks about Redis billing
- User needs to optimize memory usage
- User encounters Redis performance issues
- User needs to audit Redis configuration
- User wants to reduce Redis expenses

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
redis-cli INFO memory
Analyze fragmentation, peak memory, and eviction stats.
See cases/memory-optimization.md for optimization.
Step 2: Monitor Connections
redis-cli INFO clients
Check connection count and timeout settings.
See cases/connection-optimization.md for pooling strategies.
Step 3: Identify Hot Keys
redis-cli --hotkeys
Find keys with disproportionate access patterns.
See cases/hot-key-optimization.md for sharding strategies.
Step 4: Analyze Slow Commands
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% |
