I wonder if this includes Skywise, the Palantir-built data lake and design stack that they use for many many internal operations (design, airline support, manufacturing). Not sure what difference it really makes where the data is hosted if the folks doing the hosting call home to Colorado…
I'm sure there are 10 other things nearly as bad. No reason not to start the journey.
From what I've seen of Skywise, it is just a glorified SharePoint. Different systems upload CSV files that get turned into database tables. Then you can define views across these tables that other systems can consume by having them dumped to CSV and dropped on an SFTP.
Performance is not great, so you need middleware and batching anyway. As far as I am concerned, it wouldn't be a great loss if Skywise disappeared and just the SFTP with CSV:s remained.
