[rabbitmq-discuss] extremely long and weird delivery tag in amqp.js consumer

Fri Jan 10 19:09:45 GMT 2014

Hi,

We are using amqp.js library to consume messages from rabbitmq. But when we
log the delivery tag, we found them extremely long and weird (aren't they
supposed to be a long int?). For example:

"deliveryTag":{"0":0,"1":0,"2":0,"3":0,"4":0,"5":0,"6":0,"7":1,"length":8,"parent":{"0":60,"1":33,"2":68,"3":79,"4":67,"5":84,"6":89,"7":80,"8":69,"9":
