Message headers in the stream protocol

[Mc Polu]

Hello,

Thank you very much for making RabbitMQ open source and for supporting it, it is a fantastic product.

I have producers and consumers communicating via topic exchange using AMQP 0.9.1. The messages carry some metadata in the headers, for example timestamp in milliseconds from the plugin. I have created a stream queue and bound it to the topic exchange with a certain routing key. This works very well.

When I consume from a stream queue using a AMQP client, I can see data in the headers, same as if I subscribed to a topic the traditional way. However when I consume from a stream queue using the stream protocol, I cannot find a way to retrieve the headers.

Is there a way to retrieve message headers while using the stream protocol, please?

Thank you.

AMQP 0.9.1 headers should be translated to AMQP 1.0 application properties (streams use AMQP 1.0 message format to encode messages). How to access those depends on the stream client library you are using.

Could you provide a standalone program to help us figure out what is going on? Versions of the software (broker and client libraries) are welcome as well.

Thanks.

Thanks for reporting back, I'm glad it's working as expected. Please use the mailing list email address next time, this way everyone can benefit from your feedback.

Thank you, you are correct headers make their way to ApplicationProperties. I just didn't know to look there. Thank you very much for the help! I am using the C# stream client v1.2.0
