Subject Re: Is anyone using version 0.7 schema update API
Date Tue, 13 Jul 2010 08:42:20 GMT
They are not complicated, its more that they are not in the package that
they should be in.
I assume the client package exposes the functionality of the server and it
does not have the ability to manage the tables in the database that to me
seems to be extremely limiting.
When I did not see that code in place I assume that it is not complete or
that I have not got the right code drop.
>From your commetns it sounds like you don't support the Java client code
base in line with the ruby code. Which I think is limiting but is just the
way it is.
