Synchronising different of a database - django

Question

I have made a django web app (postgresql backend) for internal use for one of my clients in New Zealand. They have told me that they would also like it to be used by one of their branches in Malaysia (it will need to be connected to the same database). The problem is that apparently in Malaysia the internet is really unpredictable and there is a lot of downtime.

So here is the question, what would be the best way for keeping the Malaysian branch running when their internet is down and having their version of the database synchronised with the main database back here in NZ?

Answer 1

What you are trying to do is to synchronize your data and schema across multiple (2 in your case) postgresql databases.

There are a variety of solutions to do that depending on exactly what you want to achieve. This is a good place to start - http://www.postgresql.org/docs/devel/static/high-availability.html
