[Feature Request]: Batch Publishing

[escb005]

Using publisher confirms, sending multiple messages currently takes a lot of time since it waits for the confirmation between the individual sending.

A function that first publishes a list of messages and then waits for the confirmation would circumvent this issue.

Possible but may lead to potential out of order messages or to duplicated messages when a whole batch is republished.

Other solutions may include having a data format consisting of a list of messages which are correctly ordered but just need more memory for processing.

Would this still work if the messages are routed to different queues or even different exchanges?

[jxsl13]

A RabbiqMQ message can be up to like 2G+ big. So the big blob of multiple messages would be routed as a whole.

I do highly NOT suggest to have messages that big, it's just that you can have like somewhat bigger messages like a few 100KiB.

[jxsl13]

you'd have to preprocess your messages somewhat if possible so that each list is routed to the same destination and a single list only contains homogenous mesages.

wrapping the batch in a transaction may help but needs further investigation.
