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.
For R webscraping, check out https://github.com/feddelegrand7/ralger which is available on CRAN and builds in rvest and xml2. It simplifies the scrapping process quite a lot. I use it quite regularly and works beautifully.
