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.
In my case, we use a proprietary library similar to this: https://github.com/msitt/blpapi-python. Take a look at the examples there, they can explain better than I can :)
