[rabbitmq-discuss] Can RabbitMQ handle big messages?

No code avilable anymore but I used to test >=512MB messages, no problems at all.
(Except of coarse it takes ages to upload/download, and getting any %-complete is almost impossible)

Used py-AMQP then.

FYI & cheers

Hi guys,

Before trying to rewrite the wheel, anyone faced this problem before and would like to
share some code (ie. splitting a big file are constructing it when reading from RabbitMQ queue)?

Thanks ...

Hi, Zabrane:  In theory the AMQP protocol IIRC allows crazy large message payloads (2^64 bytes I believe).  In practice though, that's madness since you end up with potential copying and buffering along the way that could make a broker very unhealthy.

For moving bulk binary data as in your app, you'd be wise to fragment at the producer and reassemble at the destination/consumer. Keeping your chunks in the 100KB range might be a decent place to start experimenting.

Hi there,

I've a set (~1 million) of high resolution PNG files  each one between 100MB and 1GB size.
I'd like to know if RabbitMQ is capable of handling such files as messages?

What's the max allowed message size?

Thx ...
