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.
However, while it's an indirect solution, there's a "Scrolling Combat Text" (SCT) addon to the popular Arcdps damage meter. I have not tested it for a while. But if it still works, it displays damage info next to your character instead of above the ennemy, and it's reasonably customizable (color, size, font).
