Well, this time has come. Node was not merged with DbAdapter, but
instead DbAdapter is now a factory for the nodes.
After thinking about the whole QueryRunner rearchitecture, I realized
that even a node having a customizable query runner is not enough. For
instance we will not be able implement an LDAP adapter with just a
custom QueryRunner. Also in Cayenne design DataNode *was* a query
runner already - the lowest possible level of communication with the
data source. Adding another level of indirection just seemed unnatural.
I checked all the needed code for this. Now back to customizing queries
by adapter....
