Arvid Heise commented on FLINK-20127:
-------------------------------------
Migrating benchmark to new source interface turned out to be a PITA since all
Flink dependencies are heavily outdated. The most important takeaways from the
experiments: UC is stable in 1.12 (for the Throughput job) and performs much
better than in 1.11. The full extend would only be visible through new sources.
