GenstageSqs

This is a simple example of using AWS Simple Queue Service (SQS) as the source for a GenStage producer. This elixir app creates 2 producers and 4 consumers, reads messages from the queue and then deletes them. It is a very simple and generic example used only to test the functionality of the producer.

You can read about this in my blog post Writing a GenStage producer for AWS SQS

Testing

To run this example you will need to set the AWS keys as env variables in the command line or add them to the config/config.exs instead of the system envs. See ExAws docs for options for configuration.

1. Run AWS_ACCESS_KEY_ID=your_access_key AWS_SECRET_ACCESS_KEY=your_secret_key iex -S mix
2. Enter iex(1)> GenstageSqs.create_messages(10)

This will cause the producers to start pulling messages from SQS and sending them to the consumers. You can add more of each (producers & consumers) to process more messages or create less to process less messages.
