        ModelA.count().exec(function(err, count) {
          if (err) return done(err);
          if (count > 0) return done();
          ModelA.create(modelA).exec(done);
        });
      },
      function(done) {
        var modelB = [{ "name": "testB" }];
        ModelB.count().exec(function(err, count) {
          if (err) return done(err);
          if (count > 0) return done();
          ModelB.create(modelB).exec(done);
        });
      }
    ], done);
  }
  createMysqlTestData(cb);
  
};

Is there is any particular way to switch amongs different Db's prgramatically?
Im planning to give Separate Db's for each of my Signed up users.

Is there a way to create FK in the different DB using the mySql-adapter?
