You can load it with different gear you might equip, allies that you'd like to accompany you, spells you might cast, weapons to help you battle the strange monsters you encounter, talents you can develop, and events that might grant you valuable momentary advantages. You'll have a good measure of freedom in the design of the rest of the deck. ( Core Set, 15), as well as a basic weakness-possibly In Wendy's case, this means her deck will always include ( Core Set, 5), each investigator comes with deckbuilding requirements that include two character-specific cards and a weakness. Some of these are indicated by your double-sided investigator card. Regardless of which investigator you become, you'll begin play with a number of different strengths and weaknesses. You might assume the persona of Federal Agent Roland Banks, or you might slip into the role of street urchin Wendy Adams. CircuitState.In Arkham Horror: The Card Game, you become one of the unlikely group of investigators living and working in or near the quiet New England town of Arkham. * CircuitState.Closed - Normal operation. Monitor the circuit state, for example for health reporting.

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.

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.
