This is the case at the moment anyway. The problem is that each database
is encoding its own way long strings of data.
It is not the same encoding from postgres as it is with mysql, as it
with hypersql or other databases.
We have chosen to encode data a way that is supported by all databases,
and indeed you can't read the blobs again if you're not using c-jdbc
anymore.
But if we don't go this approach then I don't how we can support
heterogeneous clusters of databases.
At the moment, we are also trying to implement streaming of data only if
the underlying driver supports streaming.
Please, share with us ideas on the c-jdbc mailing list if you have the
time. Critics are welcomed.
