While I appreciate your taking the time to make suggestions, these suggestions aren't very useful without context. I'm not saying that it's up to you to provide the context. But I don't know much about Flink or Heron, and looking at their respective websites doesn't tell me whether they'd be a good fit for a specific use case.

At this point, all of these frameworks would probably benefit from a flowchart (or questionnaire tool) that can guide someone towards an informed decision. "Do you need redundancy?" - "Can you afford to lose some messages in situation XYZ?" - "How many events/sec do you want to process?" - "How much hardware can you throw at the problem?" etc.

The situation is actually more complex than you are suggesting. A check box comparison is not useful. I have worked in considerable depth in the streaming space and my comments are based off the design docs of both systems. You should read Twitter's heron paper and Apache Flink design docs.

For eg, storm or samza might check all the boxes, but the design of the system is poor enough that the performance will suck. For older versions of Storm, you should be able to write a multithreaded app on a single machine that outperforms a storm cluster.
