Description

The newly introduced reactive mode (FLINK-10407) allows Flink to make use of newly arriving resources while the job is running. The feature documentation with the current set of limitations can be found here [1].

In order to test this new feature I recommend to follow the documentation and to try it out wrt the stated limitations. Everything which is not explicitly contained in the set of limitations should work.
