[rabbitmq-discuss] Help required: How to keep the length of a message in bytes

Fri Mar 23 11:31:43 GMT 2012

Dear Emile,

Actually I am understanding by implemeting a kind of working of this RabbitMQ message. I actually want to simulate some of the basic ideas of this. What important features of the message I should consider. I want to keep the length of the message to estimate how much time an exchange would take to process it in my simulation. I dont know whether I am describing it properly or not. 

Thanks for help. 

Saima

I'm not sure I understand your question. What are you trying to do?

The length of the message body (byte array) will normally exceed the
length of the routing key. Message headers and internal accounting
fields also contribute to the overall memory and/or disk footprint of a
message.

If you are performing a scoping exercise to estimate the amount of RAM
required then use the expected message body size instead of the routing key.
