Ballista 0.3.0 is now available10 Aug 2020
The goal of the 0.3.0 release is to provide a minimum viable product of distributed compute in Rust. It is now possible to run a query that is very close to TPC-H query 1 on a distributed cluster with reasonable performance. Performance and scalability is comparable to Apache Spark (within the range of 2x slower to 2x faster based on initial benchmarks).
Performance tuning will be one of the main areas of focus for the 0.4.0 release.
