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.
Note that you can install evcxr and use it as a Rust REPL in your terminal (see https://github.com/google/evcxr/blob/main/evcxr_repl/README.... ). (Tip: alias it to something that you'll actually remember how to type!)
How cool. This motivated a quick search - this could be fun:
How to write your own kernel

All the language kernels (a lot of abandoned ones - the mariaDB one ('binder') will take a while to load but SQL in Jupyter!)

My usage is very narrow (aggregating a dataframe of bounding box observations over a sliding time window) and I only use streaming Arrow IPC, which both work great!
