SQS Queues Proxy

This is a work in progress, and a learning project.

This project's purpose is, given an SQS queue A, take all the messages it receives and send them to queues B, C, etc; deleting them from A in the process.

It is configurable through a JSON file, being able to listen to several queues, and set several recipient queues per source.

Currently it only works within a single AWS account.

Sample config.

Assuming we have 2 source queues (A and B), and want to proxy all messages that A receives to queues C and D, and all messages that B receives to D, E and F; the config file would look like:

{
    "proxyOps": [
        {
            "src": "https://sqs.region.amazonaws.com/accountid/A",
            "dest": [
                "https://sqs.region.amazonaws.com/accountid/C",
                "https://sqs.region.amazonaws.com/accountid/D"
            ],
            "interval": 20
        },
        {
            "src": "https://sqs.region.amazonaws.com/accountid/B",
            "dest": [
                "https://sqs.region.amazonaws.com/accountid/D",
                "https://sqs.region.amazonaws.com/accountid/E",
                "https://sqs.region.amazonaws.com/accountid/F"
            ],
            "interval": 35
        }
    ]
}

The attribute interval specifies the number of seconds to wait between polls to that particular source queue.

AWS Credentials

This project relies on AWS SDK fetching your AWS Credentials. Look at their docs for more info

Running the proxy

The proxy is called with a --config flag that points to the JSON config file to use.

go build .
./sqs_proxy --config ./config.json

TODO

• Extend unittests
• Make it possible to proxy messages to the recipient queues in a round robin fashion. Consider a random recipient method as well.
• Make the long-polling time configurable
• Set up CI
• Consider storing some metadata on the messages proxied
