How to configure messages to be re-sent in case Queue size limit Exceeded

[Arun Sathayanarayanan]

Hi Everyone,

I want to design a retry mechanism in case of the messages are undelivered  because  of queue already holding a x-max-length-bytes of contents.

When i go thru literature, i understand that we can set the mandatory field in amqp_basic_publish method and broker would respond with amqp_basic_return_t frame to indicate the reply code set to 311 content-too-large . Reference

(https://www.rabbitmq.com/amqp-0-9-1-reference.html#domain.reply-code)

The psuedo code would look like below at the client side

//sending the message to the broker

amqp_basic_publish(conn,chan,exchange,route_key,1,0, prop,body);

//wait for frame to ensure there is no ExceedResource indicators

amqp_simple_wait_frame(conn,&frame)

if( frqme.tye is AMQP_FRAME_METHOD and  method id is AMQP_BASIC_RETURN_METHOD and reply_code is 311)

   resend the frame

My Question

In case broker delivers the message to the queues successfully, will client be intimated with a success. Can we do this without enabling  publish confirm.  

 

Using amqp_simple_wait_frame in publisher side throttles it, and will have impacts in terms of performance. Are there any alternatives to this strategy.

Thanks in Advance
