Maximum message size for RabbitMQ

Question

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

I do not see any obvious limitations in the documents, but I assume that there are some recommendations.

Thanks in advance.

Answer 1

I did a comparison between the Amazon Queuing Service and RabbitMQ or other streaming + messaging platforms such as kinesis, kafka. Since the Amazon queue service only supports min 2^10 bytes(1 Kilobytes) - max 2^18 bytes (256 Kilobytes) , similarly, kinesi has size limits. (Don't know why?)

In any case, in theory, AMQueueProtocal will handle 2^64 bytes . Thus, even for a huge message, RabbitMQ can work in one broker, definitely taking minutes / hours to save, but it may or may not be in a cluster of brokers. If message transfer time between nodes (60seconds?) > heartbeat time between nodes , this will disconnect the cluster and release the message.

This thread is useful -> Can RabbitMQ handle large messages?
