Question

I am using node+typescript+amqplib to build a project with rabbitMQ cloud service, if the QUEUE have 5 messages to consume, I use the code : channel.consume(queue, (msg) => {... } to consume the messages, I will get all the 5 messages in one time. how can I limit the number of message of AMQP in one time of consume? I mean, if I can limit one time 2 messages, I can get 2 messages at the first time, then get 2 at the second time, then 1 at the 3rd time, could you help me~
