Tags: sql-engine, distributed-systems, rust, trino, query-engine, federated-queries

Score: 7.8/10 (Innovation: 7, Technical: 9, Documentation: 8, Utility: 7)

Arneb is a Rust implementation of a Trino-compatible distributed SQL engine, featuring federated querying across heterogeneous data sources. It demonstrates impressive performance gains (2.3x faster warm, 0.14x memory vs Trino) on the full TPC-H benchmark, with a single self-contained binary and no JVM overhead. The project is technically ambitious and well-documented, but remains early-stage (10 stars) and needs community adoption to prove its long-term viability.

Target audience: data engineers, backend developers, devops
