# Cost Reduction Strategies

## Cost Reduction Strategies

### Step 1: Request Sampling
```typescript
function shouldSample(samplingRate = 0.1): boolean {
  return Math.random() < samplingRate;
}

// Use for non-critical telemetry
if (shouldSample(0.1)) { // 10% sample
  await supabaseClient.trackEvent(event);
}
```

### Step 2: Batching Requests
```typescript
// Instead of N individual calls
await Promise.all(ids.map(id => supabaseClient.get(id)));

// Use batch endpoint (1 call)
await supabaseClient.batchGet(ids);
```

### Step 3: Caching (from P16)
- Cache frequently accessed data
- Use cache invalidation webhooks
- Set appropriate TTLs

### Step 4: Compression
```typescript
const client = new SupabaseClient({
  compression: true, // Enable gzip
});
```
