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.
I wouldn't want to work on data in C either... Ipython is a "prettified" for interactivity Python shell (I think this is what REPL means?) but to me it does not feel like the best development environment. Have you tried any "notebook" interfaces (they look a bit like Maple or Mathematica, with both code and results on one page). Jupyter is huge in Python, you can try it easily in Google Colab. There is a project for a clojure kernel for jupyter, but it looks not quite done: https://github.com/clojupyter/clojupyter. And finding the problem across languages when something breaks does not sound fun.
