I recommend reading the Polly wiki for more information for details and mechanics around the patterns we provide. There are two events, onSuccess/onFailure, that are called when a call succeeds or fails. Note that onFailure only is called if a handled error is thrown.

backoff - The exponential backoff algorithm in Go (Golang).

•    Go

---

This is a Go port of the exponential backoff algorithm from Google's HTTP Client Library for Java. Exponential backoff is an algorithm that uses feedback to multiplicatively decrease the rate of some process, in order to gradually find an acceptable rate. The retries exponentially increase and stop increasing when a certain threshold is met.

circuitbreaker - Circuit Breakers in Go

•    Go

---

Circuitbreaker provides an easy way to use the Circuit Breaker pattern in a Go program.Circuit breakers are typically used when your program makes remote calls. Remote calls can often hang for a while before they time out. If your application makes a lot of these requests, many resources can be tied up waiting for these time outs to occur. A circuit breaker wraps these remote calls and will trip after a defined amount of failures or time outs occur. When a circuit breaker is tripped any future calls will avoid making the remote call and return an error to the caller. In the meantime, the circuit breaker will periodically allow some calls to be tried again and will close the circuit if those are successful.

VoltDB - Fast Scalable SQL DBMS with ACID

•    Java

---

VoltDB was specifically designed for contemporary software applications that are pushed beyond their limits by high volume data sources. VoltDB provides the ability to capture, store and process incoming data at millions of read/write operations per second. And VoltDB’s relational model opens that data to be analyzed in real-time, using familiar Business Intelligence tools, to identify data patterns and trends, spot anomalies, or perform tracking and alerting.

hyperf - 🚀 A coroutine framework that focuses on hyperspeed and flexibility

•    PHP

---

Hyperf is an extremely performant and flexible PHP CLI framework based on Swoole 4.5+, powered by the state-of-the-art coroutine server and a large number of battle-tested components. Aside from the decisive benchmark outmatching against PHP-FPM frameworks, Hyperf also distinct itself by its focus on flexibility and composability. Hyperf ships with an AOP-enabling dependency injector to ensure components and classes are pluggable and meta programmable. All of its core components strictly follow the PSR standards and thus can be used in other frameworks. Hyperf's architecture is built upon the combination of Coroutine, Dependency injection, Events, Annotation, AOP (aspect-oriented programming). Core components provided by Hyperf can be used out of the box in coroutine context. The set includes but not limited to: MySQL coroutine client, Redis coroutine client, WebSocket server and client, JSON RPC server and client, gRPC server and client, Zipkin/Jaeger (OpenTracing) client, Guzzle HTTP client, Elasticsearch client, Consul client, ETCD client, AMQP component, Apollo configuration center, Aliyun ACM, ETCD configuration center, Token bucket algorithm-based limiter, Universal connection pool, Circuit breaker, Swagger, Swoole Tracker, Snowflake, Simply Redis MQ, RabbitMQ, NSQ, Nats, Seconds level crontab, Custom Processes, etc. Be assured Hyperf is still a PHP framework. You will also find familiar packages such as Middleware, Event Manager, Coroutine optimized Eloquent ORM (And Model Cache!), Translation, Validation, View engine (Blade/Smarty/Twig/Plates/ThinkTemplate) and more at your command.

Resilience4j - Fault tolerance library designed for Java8 and functional programming

•    Java

---

Resilience4j is a lightweight fault tolerance library inspired by Netflix Hystrix, but designed for Java 8 and functional programming. Resilience4j provides higher-order functions (decorators) to enhance any functional interface, lambda expression or method reference with a Circuit Breaker, Rate Limiter, Retry or Bulkhead. You can stack more than one decorator on any functional interface, lambda expression or method reference. The advantage is that you have the choice to select the decorators you need and nothing else.

lyra - High availability RabbitMQ client

•    Java

---

Dealing with failure is a fact of life in distributed systems. Lyra is a RabbitMQ client that embraces failure, helping you achieve high availability in your services by automatically recovering AMQP resources when unexpected failures occur. Lyra also supports automatic invocation retries, recovery related eventing, and exposes a simple, lightweight API built around the RabbitMQ Java client library.Please note that Lyra and RabbitMQ Java client's recovery feature are mutually exclusive and must not be used together. Note that RabbitMQ Java client 4.0 and later versions have automatic connection recovery enabled by default.
