Retry Mechanism
A mechanism in production systems that automatically re-executes failed operations to handle network fluctuations, API rate limiting and temporary failures. It is typically combined with backoff strategies and idempotent design to avoid duplicate side effects.
Timeline (last 90 days)
The prerequisite for a single step to be retryable is that the step is idempotent, that is, repeated execution with the same input does not produce accumulated side effects.
Retry mechanisms automatically resend requests when a model returns a timeout or error, and each retry consumes tokens.
Retry logic must be paired with backoff and circuit-breaking mechanisms; blind retries will multiply pressure many times over in failure scenarios.
When a service configured with a maximum of 3 retries receives errors from downstream, the actual volume of requests reaching the downstream service may instantly amplify to 3 to 4 times the normal level.
In multi-layer call chains, the amplification effect of retries accumulates layer by layer, causing the pressure borne by underlying services to grow exponentially.
Proper retry handling requires distinguishing retriable transient faults from logical errors that should not be repeated; otherwise, blind retrying may amplify the problem.
