Re: django synchronize database over REST

If you're not using synchronous replication (ie, something like a two-phase commit, or something very close to it), then it is impossible to come up with a generic solution for replication. you might be able to "come close", but how to deal with desync is application specific.

Ie, say you had two users do a thing on both systems, but the thing is contradictory, and thus cannot be replicated. How do you solve this "in the background" ?? Well, that's something that can only be decided by the application. And, in fact, what actions are considered contradictory is also application-specific.

So, for the most part you're going to have to come up with it yourself.

So I have this 2 applications connected with a REST API (json messages). One written in Django and the other in Php. I have an exact database replica on both sides (using mysql).

My question is, how can i keep this 2 applications databases synchronized?

In other words, when i press "submit" on one of them, i want that data to be saved on the current app database, and on the remote database for the other app using rest.

Is there a django app that does that? i read about django-synchro but didn't see anything REST related.

And i would like to keep things asynchronous, in other words the user must be able to keep using the app while this process is running on the background and keeping data consistent.
