We are using Amazon MQ which internally use ActiveMQ. We can trigger AWS lambda function whenever ActiveMQ receives a message. I wrote a lambda function which reads the message from an SQS event. We have a type called SQSevent which we can capture, but in the case of Amazon MQ I don't know what type of function signature to be used.

For SQS we use this:

ProcessSQSMessage( SQSEvent event1, ILambdaContext context)

I don't know what to use for Amazon MQ:

?ProcessMQMessage( ?? )

Please help. I don't have access to AWS from local so checking before deploying code.

Currently, there is no out of the box event for MQ according to the docs To work with AWS you can follow this recommendation and as described either:

  • use default handler with Stream parameter and convert Stream to a C# class messages. This is how the handler will look like:

    public Stream MyHandler(Stream stream, ILambdaContext context)
     {
        //converting Stream into MQEvent and function logic
     }

  • Create a custom implementation of ILambdaSerializer. Then decorate your lambda class with [assembly: LambdaSerializer(typeof(CustomInputDeserializer))]
