It is indeed interesting, and it's from Nathan Marz, who was the creator of Storm. That was the first major open source streaming platform. It predated what I consider the default open source streaming platform, Flink. Glancing through the docs, my main three reactions are: 1) It's sophisticated system which, as you say, effectively opens up the components of a database engine to be used as needed. 2) Folks will still want to eventually land their data in a "normal" data-at-rest storage format like Hive tables or Parquet. 3) Folks will still want SQL.
