Yes, I pretty much agree with it. In fact I would replace Spark with Kafka.
Apparently (I know next to nothing about it but I'm reading one of the other posters' comments) Spark and Kafka can be used in tandem and have synergies.
I think Spark, for real-time web dev, needs something like Kafka so starting there is a great idea.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
