As much as I love seeing competition in the space and am enjoying my popcorn, I really don't understand what Databricks is doing here: this feels like a childish foodfight rather than an obsession with the customer...
I believe the co-founders have addressed this in the blog.
> Our goal was to dispel the myth that Data Lakehouse cannot have best-in-class price and performance. Rather than making our own benchmarks, we sought the truth and participated in the official TPC benchmark.
I'm sure anybody seriously looking at evaluating data platforms would want to look at things holistically. There are different dimensions like open ecosystem, support for machine learning, performance etc. And different teams evaluating these platforms would stack rank them in different orders.
These blogs, I believe, show that Databricks is a viable choice for customers when performance is a top priority (along with other dimensions). That IMO is customer obsession.
* I haven't executed the test suite, but fraud seems likely.
Both participants in a fight can win by implicitly excluding their real competitors.
EDIT: I forgot lying about how open they are when all their interesting technologies (like the new sql engine and the good parts of delta) are proprietary.
