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 setup.py 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.
Example:
# my_consumer.py
def my_callback(message):
print('Got a message! Contents:', message)Then on the command line:
$ squishy run_consumer https://sqs.us-east-1.amazonaws.com/12345/my_queue 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.
