The project draws inspiration from DataFusion Comet (a Spark accelerator) and existing projects like Arroyo and RisingWave, porting their Rust-native streaming operators to work with Flink's planner. The author is using Claude (AI coding assistant) heavily to generate code, relying on Flink's existing test suite and Nexmark benchmarks for validation. The goal is to achieve 1.5–3x performance improvements over standard Flink SQL, with an AI-driven issue response loop planned to keep development velocity high. The project was just open-sourced on GitHub with ~300 commits already. ## Full article daily.dev links to this article rather than hosting it.
