Order of Resilience Decorators
Learn why the order in which you stack resilience patterns (retry, circuit breaker, bulkhead, timeout, rate limiter) changes behavior, and how to choose the right ordering.
Stacking Patterns
Resilience libraries let you wrap a call in multiple patterns at once: retry, circuit breaker, bulkhead, time limiter, rate limiter. The patterns form a chain, and order matters.
The same set of patterns produces different behavior depending on how they are nested.
Decorators as Layers
Think of each pattern as a layer wrapping the next. The outermost layer sees the call first; the innermost actually invokes the dependency.
layers = ['Retry', 'CircuitBreaker', 'Bulkhead', 'TimeLimiter', 'ServiceCall']
for i, l in enumerate(layers):
print(' ' * i + l)All lessons in this course
