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.
anyways, if you REALLY need to do that in PDFs, dochub.com (has a free plan) or pdffiller.com (has a free trial of one month) is your go-to, imho
