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.
Unfortunately, since Eta is no longer maintained and Frege never was quite Haskell, there's no Haskell implementation on the JVM, so you either have to make due with "impure" Scala/Kotlin or make the jump to the Idris2 JVM backend (https://github.com/mmhelloworld/idris-jvm).
