16.11.2023 How to build a scalable streaming data pipeline for financial big data

High-quality historical financial data offers a direct competitive advantage in the systematic trading business, but its big data qualities make it both costly to manage and store as well as very expensive to buy from external sources. To mitigate a part of these expenses, a custom, self-managed data lake can be built by recording and storing real-time financial data through a scalable streaming data pipeline.
