Streaming Data in DuckDB: Conquering Concurrency Limits with Arrow Flight

Definite's blog post showcases a clever solution to overcome DuckDB's concurrency limitations using Apache Arrow Flight. While DuckDB excels at single-machine analytics, its lack of concurrent writer and reader support restricts its use in real-time streaming scenarios. The 'Duck Takes Flight' Python script builds an Arrow Flight server, enabling concurrent writes and reads to DuckDB. This 200-line solution is efficient, requiring no complex cluster setup, and delivers high-performance stream processing, offering a fresh approach for applications needing fast data movement and on-the-fly querying.
