Loafer
Loafer is an asynchronous message dispatcher for concurrent tasks processing.
Currently, only AWS SQS is supported
Features:
Encourages decoupling from message providers and consumers
Easy to extend and customize
Easy error handling, including integration with sentry
Easy to create one or multiple services
Generic Handlers
Amazon SQS integration
It requires Python 3.6+ and is very experimental at the moment, expect a lot of changes until the first major version.
Example
A simple message forwader, from source-queue to destination-queue:
from loafer.ext.aws.handlers import SQSHandler
from loafer.ext.aws.routes import SQSRoute
from loafer.managers import LoaferManager
routes = [
SQSRoute('source-queue', handler=SQSHandler('destination-queue')),
]
if __name__ == '__main__':
manager = LoaferManager(routes)
manager.run()Documentation
