Sail is a drop-in Apache Spark replacement written in Rust, unifying batch processing, stream processing, and compute-intensive AI workloads on a distributed, multimodal compute engine. Compatible with the Spark Connect protocol, supporting the Spark SQL and DataFrame API with no code rewrites required. 100% Rust-native with no JVM overhead, delivering memory safety, instant startup, and predictable performance. ~4× faster (up to 8× in specific workloads) than Spark and 94% cheaper on infrastructure costs. See derived TPC-H benchmarks. Proven on ClickBench, outperforming Spark, popular Spark accelerators, Databricks, and Snowflake. Documentation
