> Delay the creation of actual function to send to a physical stream until

> Reporter: Yi Pan (Data Infrastructure)

> Labels: fluent-api

> 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
