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.
Other poster listed basics rather well. I recommend to check computer-science curriculums that go with python. You will find plenty of content, I know edx.org offers free video courses but personally I recommend to read papers/books to get all the basics and reproduce stuff in your own projects. A quick google gave me this as an example: https://github.com/Akuli/python-tutorial (github has great content)
