horrible performance, maybe doing joins within Cayenne SQLAction code

Taking a brief look at SQLAction -- Is there a way to register an
observer/delegate with the engine from the application that can return
an alternate query to execute?
One way to customize SQLAction is to subclass a query itself
overriding 'createSQLAction'. But this won't work for relationships
of course.
Alternatively you can use DataConextDelegate to intercept the queries
and if needed wrap them in a custom decorator that builds the right
SQLAction (check various indirect queries on how the decorator might
look like, e.g. ObjectIdQuery).
