Hi Michelle,

This sounds a lot like simple replication.

There are a few PostgreSQL replication solutions in existence, with a
summary of them available here:

What do you mean?

If you're wondering how much traffic will happen, it depends on which
replication solution you use, and how many changes happen to your master
database in Paris.

Does this help?

:-)

Regards and best wishes,
