no-ack = False,如果消费者遇到情况(its channel is closed, connection is closed, or TCP connection is lost)挂掉了,那么,RabbitMQ会重新将该任务添加到队列中。 RabbitMQ是默认开启自动应答的,这样当rabbitMQ将消息发给消费者,就会从内存中将消息删除,这样会带来一个问题,如果消费者未处理完消息而宕机,那么消...

源码:https://github.com/ltoddy/rabbitmq-tutorial Topics (using the Pika Python client) 本章节教程重点介绍的内容 在之前的教程中,我们改进了日志记录系统。我们没有使用只有虚拟广播的fanout交换,而是使用了direct交换,并让选择性接收日志成为了可能。

RabbitMQ Stream provides a special mode to publish, store, and dispatch messages: sub-entry batching. This mode increases throughput at the cost of increased latency and potential duplicated messages even when deduplication is enabled. It also allows using compression to reduce bandwidth and storage ...
