A simple Amazon SQS consumer library.

Project description


Squishy is a simple Amazon SQS consumer for Python. Many versions of Python are (or will be) supported.

This is currently alpha software! It works under basic testing but does not yet have a full battery of automated tests. Use at your own risk!


Currently, you have to clone the repo and install the hard way. This will change soon.

  • Clone the repo.
  • Install the requirements. If you want to use the futures workers on Python 2, be sure to install futures.
  • python install


Squishy provides a CLI to run a worker that will dispatch messages to a callback you define. The callback should accept a single parameter representing a single message consumed from an SQS queue.



def my_callback(message):
    print('Got a message! Contents:', message)

Then on the command line:

$ squishy run_consumer my_consumer:my_callback


Squishy uses boto3, which will automatically load credentials from $HOME/.aws/credentials. If you need more control over authentication, you can give Squishy a factory function for creating a custom session.
