Hi everybody,

We are building a prototype of our first Hardware system. It's a sensor that we expect to send data approx. every 5 secs. If we scale it to about 1k sensors, it would mean 173M records per month.

We will offer data-retention for 7 days or 1 month based on the plan, but if by any chance the project goes well I see that we can have a lot of pain if not choosing the persistence layer correctly from day 1. Which data storage would you use for that?

Cheers, Alberto.
