Yes. > Would that mean ConnectionPool would extend Pool and we would deprecate Pool > itself? Maybe extend. I worry about extending, for two reasons. First, extending would make the new interface depend on the deprecated one. That feels awkward for reasons I can’t articulate Second, extending would mean that the new interface gets all the methods of the deprecated one whether we want them or not. I don’t know enough about Pool to have an opinion about whether we want to carry all of its method signatures forward. An alternative to consider: Each ConnectionPool implementation delegates to a Pool. I suspect that this would make it harder to migrate existing uses from Pool to ConnectionPool. — Dale Emery dem...@pivotal.io
