How to import and export messages to queue in RabbitMQ

[Send Kanoon]

We are developing a system which uses rabbitMQ for sending and receiving data between its clients and servers.
The internet connection may sometimes be lost.

1- Can all the messages in the queue be exported to a file ? And somehow be imported to the client using this file?

2- In a different scenario, a client wants to send some messages to the queue but it has no internet connection! So we want to export all the message from client and make a file and somehow send it to the server (eg. transfer it to another location which has internet), Is this possible to import this file to the queue?

See [1] and [2] (I'm not assuming you use the Java client here but it's a good overview of a feature multiple clients provide these days).

You can "archive" published messages however you please locally and republish them when connection recovers. Some publish to a local

RabbitMQ node and use Shovel [3] to move data to a remote location, letting Shovel worry about reconnection and recovery. It's not a perfect

tool but unless the network is really bad it usually does a decent job. Also relevant here: [4].
