RabbitMQ 的最大消息大小

问题描述

发布到 RabbitMQ 队列(发布/订阅模型)时消息的最大大小是多少?

What is the maximum size that a message can be when publishing to a RabbitMQ queue (pub/sub model) ?

我在文档中看不到任何明确的限制，但我认为有一些指导方针.

I can't see any explicit limits in the docs but I assume there are some guidelines.

推荐答案

我在 Amazon Queue Service 和 RabbitMQ 或其他流式 + 消息传递平台(如 kinesis，卡夫卡.由于 Amazon Queue Service 仅支持 min 2^10 bytes(1 Kilobytes) - max 2^18 bytes (256 Kilobytes)，同样的 kinesis 也有大小限制.(不知道为什么?)

I was doing comparison between Amazon Queue Service and RabbitMQ or other streaming+messaging platforms like kinesis, kafka. As Amazon Queue Service only supports min 2^10 bytes(1 Kilobytes) - max 2^18 bytes (256 Kilobytes), similarly kinesis has size limits too. (Don't know why?)

无论如何理论上AMQueueProtocal 将处理2^64 字节.因此，即使对于大消息，RabbitMQ 也可能在单个代理中工作，肯定需要几分钟/小时才能持久化，但可能会或可能不会在代理集群中.如果节点之间的消息传输时间(60秒?)>节点之间的心跳时间，会导致集群断开和消息丢失.

Anyway In theory AMQueueProtocal would handle 2^64 bytes. So, even for a huge message, RabbitMQ might work in a single broker, definitely taking minutes/hours to persist but would or might not in a cluster of brokers. If the message transfer time between nodes (60seconds?) > heartbeat time between nodes, it will cause the cluster to disconnect and the loose the message.
