Hi DB mediator can be handy as you said but it is a bad practice to query the DB right from the Esb. It is against the low coupling principles that makes integration layer agile and thin and scalable etc.
DSS is setup in two minutes and can fulfill your needs out of the box. Maybe we should provide a migration tool to turn DBMediator usage into Daraservices operation call. One could even generate the dbs Dataservice definition from the DBMediator. +1 for deprecating these mediators. Setup some tool or complete documentation to migrate existing usage.
