1) Why would you want to maintain your own Spark infrastructure? Spark on Kube is a huge improvement over YARN but you still have to deal with OOMEs, filled disks, Kube upgrades, pushing custom images to container registries, etc etc etc.
2) Snowflake is probably 10-50x as performant as Spark for data manipulation. I don't know what kind of unholy demonic incantations Snowflake is doing on the backend to support their SQL performance, but it's really freaking fast. There's just no other way to cut it.
I've spent 5-10 years eking every ounce of performance I can get out of a Hadoop/Spark cluster. I'm not trying to be unreasonable about this. I would love for OSS to be competitive; it's great for the world, and it would be great for my skill set and earning potential.
But it's not a contest, and if you think standalone Spark is going to be a viable competitor in a couple years, you are deluding yourself. Make informed choices about your career and investment.

Wow is this for a fact? I haven't used either in a while but I saw the blog post from databricks and Spark was more performant than snowflake.
I assumed that's what I'll also get when i run spark on kube
My only concern is that they offer just a managed cloud product. That's cool for startups, but large enterprises sometimes need more governance and ownership than that.
