I have a fanout exchange (Fanout) linked to 2 other exchanges (A, B).
I would like the fanout exchange to add the message header "x-delay: 30000" before adding the message to exchange A. Is there any way of doing this? In the management console, in the "Add binding from this exchange" I've tried adding the Argument x-delay, 30000, Number but that doesn't seem to work.
I'm using RabbitMQ 3.8.19 and the management console plugin.
Clarification: Exchange A is a RabbitMQ Delayed Message Exchange. Essentially I want messages on A to be delayed.
The obvious answer is to submit the delay on the initial message on the fanout exchange. However, what I really want is to have A have a 30 second delay, B to have a 10 second delay, etc. So I'd like to have that flexibility if RabbitMQ can support this at the fanout binding layer
