Hi Andre, the signature has been changed to enable re-materialization of that source. This allows to freely share the source between various parts of the code. I would suggest not only wrapping the ResultSet in a source but also query execution. In that case materializing such a source would run a DB query and fetch results - making it reusable.
BTW, I think pre-release versions of Slick 3 come with the reactive-stream interface implementation, which means you can use Slick with akka-streams directly. Did you considered using Slick 3?
