name	how does it work?	Premise
Retry	repeats failed executions	Many faults are transient and may self-correct after a short delay.
Circuit Breaker	temporary blocks possible failures	When a system is seriously struggling, failing fast is better than making clients wait.
Rate Limiter	limits executions/period	Limit the rate of incoming requests.
Time Limiter	limits duration of execution	Beyond a certain wait interval, a successful result is unlikely.
Bulkhead	limits concurrent executions	Resources are isolated into pools so that if one fails, the others will continue working.
Cache	memorizes a successful result	Some proportion of requests may be similar.
Fallback	provides an alternative result for failures	Things will still fail - plan what you will do when that happens.
