Error Recovery Orchestrator

Orchestrates error recovery with circuit breakers, retry policies, fallback chains, and graceful degradation.

Decision Framework

When to Apply

Use when: Distributed systems, critical operations needing reliability, external API integrations, payment processing

When NOT to Apply

Don't use when: Simple try/catch sufficient, non-critical operations

Anti-Patterns

1. No Retry Limits

// BAD: Infinite retry
while (true) { await retry(); }

// GOOD: Bounded retry with backoff
for (let i = 0; i < maxRetries; i++) {
  try { return await operation(); }
  catch (e) { await sleep(Math.pow(2, i) * 1000); }
}

2. Swallowing Errors

// BAD: Silent failure
catch (e) { }

// GOOD: Log and handle
catch (e) { logger.error('Operation failed', { error: e }); throw e; }

Trigger Phrases

• "Error handling"
• "Retry logic"
• "Circuit breaker"
• "Fallback strategy"
• "Graceful degradation"

Patterns

Circuit Breaker

class CircuitBreaker {
  constructor(threshold = 5, timeout = 60000) {
    this.threshold = threshold;
    this.timeout = timeout;
    this.failures = 0;
    this.state = 'CLOSED';
    this.nextAttempt = 0;
  }

  async execute(fn) {
    if (this.state === 'OPEN') {
      if (Date.now() < this.nextAttempt) throw new Error('Circuit is OPEN');
      this.state = 'HALF_OPEN';
    }
    try {
      const result = await fn();
      this.onSuccess();
      return result;
    } catch (error) {
      this.onFailure();
      throw error;
    }
  }

  onSuccess() { . = ; . = ; }
  () {
    .++;
     (. >= .) {
      . = ;
      . = .() + .;
    }
  }
}

Fallback Chain

async function withFallbacks(operations) {
  for (const op of operations) {
    try { return await op(); }
    catch (e) { logger.warn('Fallback attempt failed', { error: e.message }); }
  }
  throw new Error('All fallbacks exhausted');
}

Error Classification

Category	Recoverable	Retry	Example
Network	Yes	Yes	Timeout, connection reset
Auth	Sometimes	No	401 Unauthorized
Validation	No	No	400 Bad Request
Rate Limit	Yes	Yes (with backoff)	429 Too Many Requests
Server	Yes	Yes	500 Internal Server Error
Client	No	No	404 Not Found
