# 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% |
