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.
Another thing you might consider is web3.py. It might not be as useful as javascript libraries (web3/ethers), depending on what you plan to build, but the concepts are all the same and, again, you can leverage existing python knowledge.
