5 Jev use cases for analytics, with real queries and datasets
Cloud is regional. (Yes, I know, they literally have regions 🙈 I mean the providers.) I ran 650k data job ads through Jev with one question: which cloud is this job's stack built on? Europe hires for Azure: 50% of the ads that name one cloud. The US hires for AWS: 50% as well. A few fun ones: - Berlin leans AWS (40%) while Germany as a whole is 54% Azure - Virginia, home of us-east-1: 77% AWS - Arkansas: 76% Google Cloud - Spain is the only big European market where AWS wins Job ads are an imperfect proxy ofc Some name several clouds (I dropped those), and there are a few false positives. Still, it matches what I see in my own network. WDYT? Does it match where you work?
I've spent the last 24h mostly playing with images and MotherDuck and it's really damn interesting what you can do once you package things in a SQL function within an analytical database. https://t.co/IvMWQfwvsQ
