I have used Redis TimeSeries a few years ago and I found it easy to use and very performant for my needs. I think it is still chugging along at my last employer. The development team is already familiar with Redis and therefore found TimeSeries simple and easy to use. None of us wanted to use ( and learn) a dedicated TimeSeries database API and business did not want an expanded footprint to maintain. So Redis TimeSeries was an excellent solution for us
