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.
I just published some articles and code that I developed after a lot of trial and error optimizing RAM, disk, processing, and development with Python around stock quotes data. Perhaps it will be useful if you decide on Python. https://github.com/scollay/caffeinated-pandas
