How works Asterisk Realtime?

I use Asterisk Realtime and have an issue reported in this post:
https://community.asterisk.org/t/how-to-ring-sequential-with-queue-app-in-asterisk-13-and-realtime/89296/2

In my conclusion this is an Asterisk issue when use Realtime, how can I understand the Realtime functionalities works to apply the correction in the source code? Has anyone documentations about it?

Github source code:

Basically I suppose if the “order by” method is changed to use the field uniqueid will solve this issue, but I didn’t understand how these code works to be able to change it, then I am looking for knowledge to do that.

This is an end user forum. .There is a mailing list and IRC channel for developers.

Note that ARA is only maintained by the community.

I suspect you will need to read the code.

Thanks @david551
