Would each device/machine have its own keyspace?
Basically, your client needs to take care of a successful creation of the

Others on this list may know better, but it might not be good to have all your
clients create a schema on initialization. They can all use it once it has been
created, but creating it should be done by a single entity. One of the issues
that can come up if you make changes to schemas at the same ti
