Ballista A modern distributed compute platform

This Week in Ballista #7

Welcome to the 7th edition of “This Week in Ballista”, a weekly newsletter that summarizes activity in the Ballista Distributed Compute project.

Ballista is a modern distributed compute platform powered by Apache Arrow and primarily implemented in Rust, but designed to provide first-class support for other programming languages, including Python, C++, and Java.

Current Focus

Now that 0.4.0 has been released, we have been working on a PR to decouple planning from execution.

There are a number of incremental improvements planned for performance and scalability for future 0.4.x releases.

Work has started on designing a Web UI for the scheduler process. This will make it much easier to debug cluster setup issues and to monitor running queries.

Ballista 0.4.1

Ballista 0.4.1 is a patch release to fix a bug when running with multiple executors.

Recent Talk

Andy Grove gave a presentation on Ballista and Apache Arrow at the New York Open Statistical Programming Meetup. The video is now available online.

Help Wanted

Please try out Ballista with your own queries and data sets and file issues for any bugs or missing features that you discover. We would really like some help improving the user guide as well.

We are also looking for help with these issues.
