Handle return value with condition Policy Step 1 : Specify the exceptions/faults you want the policy to handle Usage – fault-handling, reactive policiesįault-handling policies handle specific exceptions thrown by, or results returned by, the delegates you execute through the policy. For deeper detail on any policy, and many other aspects of Polly, be sure also to check out the wiki documentation. This ReadMe aims to give a quick overview of all Polly features - including enough to get you started with any policy. Breaking changes are called out in the wiki ( v7 v6) with simple notes on any necessary steps to upgrade.įor details of supported compilation targets by version, see the supported targets grid.We tag Pull Requests and Issues with milestones which match to NuGet package release numbers.The change log describes changes by release.Using Polly with HttpClient factory from ASPNET Core 2.1įor using Polly with HttpClient factory from ASP.NET Core 2.1, see our detailed wiki page, then come back here or explore the wiki to learn more about the operation of each policy.
In addition to the detailed pages on each policy, an introduction to the role of each policy in resilience engineering is also provided in the wiki. Things will still fail - plan what you will do when that happens.ĭefines an alternative value to be returned (or action to be executed) on failure.ĭifferent faults require different strategies resilience means using a combination.Īllows any of the above policies to be combined flexibly. Stores responses automatically in cache, when first retrieved. Some proportion of requests may be similar. This can apply to the way your system accepts incoming calls, and/or to the way you call downstream services.Ĭonstrains executions to not exceed a certain rate. Limiting the rate a system handles requests is another way to control load. "One fault shouldn't sink the whole ship"Ĭonstrains the governed actions to a fixed-size resource pool, isolating their potential to affect others. This can affect performance more widely by starving other operations of resource, bringing down the host, or causing cascading failures upstream. When a process faults, multiple failing calls can stack up (if unbounded) and can easily swamp resource (threads/ CPU/ memory) in a host. Guarantees the caller won't have to wait beyond the timeout. Protecting a faulting system from overload can help it recover.īreaks the circuit (blocks executions) for a period, when faults exceed some pre-configured threshold.īeyond a certain wait, a success result is unlikely. When a system is seriously struggling, failing fast is better than making users/callers wait. Many faults are transient and may self-correct after a short delay.
