Hi folks,
it seems the legacy “replication” [has been removed in](https://github.com/syncthing/syncthing/commit/1616edcee3dcf43f916b95aa6fda2c9fca27df8f) and a replacement in the form of [“AMQP”](https://github.com/syncthing/syncthing/commit/f283215fce1660753fba9e213a5fee8820137c0c) has been implemented.
Official docs [do not yet mention this](https://docs.syncthing.net/search.html?q=amqp).
My assumption would be, that since it is not yet documented, it’s also not to be considered as “released feature”.
Just wanted to ask before I start guessing cli params and stuff from the commits.
Cheers & Thanks for any light you can shed. Thomas

Yep. It’s not clear to me that replication needs to be an official feature at all, tbh. You don’t need it and shouldn’t use it.
We _kinda_ need it due to the peculiarities of supporting a million+ clients, but short of that it’s always better, simpler and more robust to just run two separate servers with no replication.
And if you’re running that large a Syncthing network in secret then you should probably just fork the discovery server and do what you need for your infrastructure.

I see, fair enough.
To be fair though: I wouldn’t have stumbled across this, hadn’t the CLI params for `stdiscosrv` changed. I used the (now defunct) `-replication-listen` param to disable the port binding (default “:19200”), which I think is good practice, if you do not use something (which I didn’t).
That being said: I do make it a good practice to understand what the software I run is doing (or can possibly do). Keep in mind also, that people running their own discovery/relay server do not use your infrastructure, which is a good thing for you.
Thanks for the info though - appreciated!
Cheers Thomas

So on the plus side, there’s now less stuff to disable. 🙂
