RabbitMQ queue count based on message header value

Question

I am exploring the option of getting the queue count based on the custom header value in the message. For ex, If I have a queue that has 100 messages - 25 with a custom header "CUSTHDR" and value = "Apple", 25 with header value "Orange" and another 50 with header value "Grapes", I need to be able to get the count of messages in the queue based on the header value. Something like a method that returns 50 when I run GetMessageCount("Grapes");

Any direction is greatly appreciated.

Answer 1

This is not supported by RabbitMQ.

You would have to consume all messages, group them by header to get counts, and then re-enqueue them (or reject the deliveries).
