Hi all, I am part of a research group at the University of Pennsylvania. We are researching distributed stream processing systems; in particular, we are developing a framework for checking correctness of Flink programs through differential testing.
What I want to ask you as a community of Flink users is the following: 1. What infrastructure is available for more sophisticated testing (fuzzing, random testing, differential testing, etc.) of Flink programs? 2. Do you know of some realistic Flink programs (perhaps a bit more involved than the examples that come with Flink) that are available online, and on which we can evaluate our framework? 3. What are some Flink programs that you would be most interested in seeing more rigorous verification and testing of? Best regards, Filip
