Federation Design / Thoughts

I wanted to see what you think about the deploying of an empty zone that has the master database that will never be used.

Then deploy slave and frontends to slave databases across datacenters.

The reason is so to protect the master database.

What do you think?

I’m not sure if that setup would make any difference in terms of
protection. The only different aspect would be that the master zone would
not have any local table and just a oned to proxy slave requests. Maybe it
could help you with performance issues for a large number of slaves but it
you still need slave to access the DB to create new users etc…
