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.
Shameless plug: my bc [1] has a random number generator that is much higher quality than the shell one. Because it's bc, you can generate random numbers of any size, and you can generate random reals as well.
It is also seeded.
