The Retry Pattern: A Solution to Unreliable External Resources

The Retry Pattern addresses transient failures by attempting the operation again, giving the system a second (or third, etc.) chance to succeed. The core idea is simple. If an operation fails for a temporary reason, wait a short time and try it again. By then the cause may already be gone. Many distributed systems fail in partial ways. Some requests fail while others succeed. Other systems have outages that last only a few seconds. Sending the same request again often works, so a client can survive a brief disruption
