This exercise demonstrates the power of open source tools, specifically the FDAP stack (Apache Flight, Arrow, DataFusion, and Parquet), for building a full-featured database with minimal code. By leveraging upstream libraries and tools, developers can create high-performance databases without reinventing the wheel. The example showcases how just eight lines of code can add support for SQL queries to an OLAP database using Python, highlighting the simplicity and power of the Apache Arrow project. The availability of these tools inspires others to innovate around specific domains in the database space, reflecting a commitment to open source values.
