Hi Stephan, +1 for adding this to Apache Flink!
Regarding the question if this should be committed to the main repository or as a separate one, I think it should be the main one. Previously we were discussing the idea of splitting Apache Flink into multiple repositories and I think the consensus was that it would cause more problems compared to the benefits.
