> Generally speaking, Flink applications may consist of one or more jobs, and the jobs
may want to share the data with others. In Flink, the jobs in the same application are independent
and share nothing among themselves. If a Flink application involves several sequential steps,
each step (as an independent job) will have to write its intermediate results to an external
sink, so that its results can be used by the following step (job) as sources. Although this
works, that means users have to provide external storage and explicitly write/read from it. 
> To improve the user experience, we would like to propose adding support of interactive
programming in Flink. We would like to start with Table API. And the discussion thread is
