Does the content type header in RabbitMQ have any special meaning?

Does the content type header in RabbitMQ have any special meaning, or is it only a standardized way for my producers and consumers to signal what kind of data they are sending? In other wo开发者_运维问答rds: will messages with certain content types get any special treatment, or is it just bytes, either way?

RabbitMQ doesn't use the content-type header internally at all. It's for producers and consumers to signal message types, as you guessed.
