Re: auto discovery of existing databases not working

The data nodes don't really have the concept of database.
The database is part of the table name in data nodes, but there
is no special meta data object called database in the data nodes.
So database as a meta data object only resides in the MySQL Servers.
So the question is then how the MySQL Servers spread the information
about a created database.

I don't think that creating a database on 1 MySQL Server
automatically creates it on all other nodes. But I gather it
does create it in slave nodes when there is a replication ongoing.

CREATE DATABASE doesn't do so much more than create a directory.

But again I am not 100% familiar with all the details of how
databases are spread to other MySQL Servers.
