History repeating again. Pre-big data, most event processing was done via SQL-92, some processing via custom procedural code, and the rest via DSLs like Drools and Esper. Post big-data, most processing is being done by Spark / Flink SQL, some via custom python code, and now Kasakada.

There is bigger market forces that isn't being considered here - namely that the entire database as a service margins have been nearly driving down to zero by AWS. Why do you think firebase had to sellout to Google ? Why did Parse shut down ? Simply because the big cloud vendors figured out that providing paas services at nearly the cost of the infrastructure will win them even more compute workloads which is the real money maker (especially if your are reducing your computer pricing slower than Moore's law)
