According to our documentation (https://una.io/wiki/MySQL-cluster) this is how we would implement db clustering. Well explained though but I am still in the dark as this is all new to me. I do however according to my requirements need to have this configured because my user base will be across cities, countries, I might as well say a facebook like userbase. What I need is a clear step by step example particular to my UNA platform. If I could have separated my database for example into let's say communities, now spaces will help in this regard to separate communities, but if I could have stored each space on its own database or if some of our experts can perhaps give me some advice as to how this can be done.

In this setup of Mysql cluster the whole database is always on each mysql host, so you have exact copy of Mysql Master on all Mysql Slave hosts.
Hi Alex, a big apology for the late reply, to start off with.... Many thx for the answer. Like I said in the question I posted, I am still new with database clustering and maybe I should keep it simple and later get the picture better. One master database, read and write and basically clone or instances of the master but read only. I take it load balancing will take care of the rest .... not sure but I get what you saying....Thx once more...
