I found an interesting talk by Ludvig Sandman and Bruce Zulu at Kafka Summit London 2019, ‘Using Kafka Streams to Analyze Live Trading Activity for Crypto Exchanges,’ so I decided to leverage Kafka and modify it for my own use. In this tutorial, we will use Python to send real-time cryptocurrency metrics into Kafka topics, store these records in QuestDB, and perform moving average calculations on this time-series data with NumPy.
