One of my fav companies! Dor is an amazing person, highly recommend working with them. We started to move to ScyllaDB at my last engineering job. Doing 100TB’s a day in IoT Data.

My last job was far less data than yours (more like 100's of GB/day), and it wasn't surprising it handled it with ease. I love that DB so much. So performant, and far easier to admin than Cassandra.

What is that amount of data used for?

Is it along the lines of “we want to collect all the data we can in case we want to use or analyze it at some point”, or are there real use cases?

For IIoT, there's digital twins, machine health, sensor data aggregation, and a lot more. While a lot of it can be classified as "write once, read hardly ever," it is vital for triggers, alarms, real-time failure and security alerts, and, eventually being forwarded over to analytics systems for longer-term trends.
