Microservice framework following best cloud practices with a focus on productivity.
Patron microservices can interact with other microservices, APIs and applications using a number of clients.
All clients contain integrated tracing powered by opentracing-go; any new clients should attempt to do the same.
Third-party dependencies
github.com/opentracing/opentracing-go v1.1.0
Patron provides an HTTP client which integrates tracing into all outgoing requests by wrapping the default net/http client.
Users can configure the client’s Timeout, RoundTripper and/or set up a circuit breaker.
In order to propagate the traces, the HTTP request context needs to be set.
The AMQP client allows users to connect to a RabbitMQ instance and publish messages. The published messages have integrated tracing headers by default. Users can configure every aspect of the connection.

The Kafka client allows users to create a synchronous or asynchronous Kafka producer and publish Kafka messages with tracing headers. The builder pattern allows users to configure every aspect of the connection.

Each instance of a producer or consumer requires the specification of Sarama configuration; you can use v2.DefaultConsumerSaramaConfig and v2.DefaultProducerSaramaConfig for sane defaults.
The Redis client allows users to connect to a Redis instance and execute commands. The connection can be configured using redis.Options.
Third-party dependencies
