A wrapper for connecting to RabbitMQ which constrains clients to a single purpose channel (producer or consumer) with healing for intermittent connectivity.

Project description

codecov

talus (noun) - ta·​lus | ˈtā-ləs: a slope formed especially by an accumulation of rock debris; Occasional habitat of the pika.

A wrapper for connecting to RabbitMQ which constrains clients to a single purpose channel (producer or consumer) with healing for intermittent connectivity.

Features

  • Guided separation of connections for producers and consumers

  • Re-establish connections to the server when lost

  • Constrained interface to support simple produce / consume use cases for direct exchanges

Installation

pip install talus

Examples

Creating a message class

from talus.message import message_class

@message_class(routing_key="message.m", queues=["message.q"])
class MyMessage:
    a: str

Consumer with defaults for connection and retry

with DurableBlockingConsumerWrapper(consumer_queue='queue_name') as consumer:
   for method, properties, body in consumer.consume_generator(auto_ack=True):
       pass # DO Something with the message

Consumer specifying connection and retry data

with DurableBlockingConsumerWrapper(consumer_queue='queue_name',
   rabbitmq_host="localhost",
   rabbitmq_port5672,
   rabbitmq_user='guest',
   rabbitmq_pass='guest',
   retry_delay=1,
   retry_backoff=2,
   retry_jitter=(1, 10),
   retry_max_delay=300,
   prefetch_count=1,
   connection_name='consumer connection') as consumer:
   for method, properties, body in consumer.consume_generator(auto_ack=True):
       pass # DO Something with the message

Producer with defaults for connection and retry

with DurableBlockingProducerWrapper(producer_queue_bindings=[{"routing_key": "test.m", "bound_queue": "test.q"}, MyMessage.binding()],
   publish_exchange='amq.direct') as producer:
   producer.post('test.m', {'key': 'value'})
   producer.publish_message(MyMessage(a="s")) # using the message class from an earlier example
