---------------------------------------------------

             Summary: Delay the creation of actual function to send to a physical stream until OperatorImpl instantiation
                 Key: SAMZA-1101
                 URL: https://issues.apache.org/jira/browse/SAMZA-1101
             Project: Samza
          Issue Type: Bug
            Reporter: Yi Pan (Data Infrastructure)


There are a few reasons for that:
# it helps to keep the logic StreamGraphImpl only refers to logic stream (i.e. the physical stream properties should be populated by physical ExecutionEnvironment)
# it helps to keep the OperatorSpec for sendTo() only containing spec info, not physical implementation, which allows us to swap in collection-based or file-based streams sendTo() function w/o the user program change
