This is a case where one or more inputs is optional. This can be managed by configured the input as optional. The job in this case would run every 6 hours with whatever input is available without actually waiting for any inputs. We are currently discussing about more gating primitives. Please see if the existing capability suffices. See "Optional Inputs" sections in http://falcon.apache.org/EntitySpecification.html for additional details.
@dev is the right mailing list. We dont have the @user list created. This is to allow all the dev to help with user queries as well.
