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.
Overall if you want a DIY e-reader, your best bet is to pick a low power board that supports Linux, run the most barebones system you can on it, and reduce its power usage by aggressive means (underclocking, undervolting, "deep sleep" by turning it off after X minutes of inactivity). Then for the eink part, use a barebones desktop environment, combined with a window manager meant for eink, such as epd-wm. After that, slap an ebook reader software like Foliate on top, and you're good to go.
