Hi all,

Right now, in Flink, if I call to 2 action operators (print, count,
collect, ) consecutively, Flink will create 2 independent execution plans.
A simple example:

             DataSet<String> text = env.fromElements(

                               "Some text ….",

                               );

              DataSet<Tuple2<String, Integer>> result =

                               text.flatMap(new Tokenizer())

                               .groupBy(0)

                               .sum(1);

  result.count();

  result.print();

Could you please show me the way to force Flink create only one execution
plan, so that the later operator just reuse the result of previous one, and
doesn’t need to re-compute again?

Thanks,
Do
