AWS recently (last year) released their new server-less database focused purely on time series data, Amazon Timestream. On their product page, AWS describes the database like:

“Amazon Timestream is a fast, scalable, and serverless time series database service for IoT and operational applications that makes it easy to store and analyze trillions of events per day up to 1,000 times faster and at as little as 1/10th the cost of relational databases.”
