InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
The barrier to entry (especially as a newcomer to Rust) is probably a bit higher because of async and some nightly Rust. But you could take a look at the (embassy)[https://github.com/embassy-rs/embassy/] project. It's a bit more high-level and comes with an executor that handles concurrency and timers for you (using async).
