Ray Meetup: A Year of Distributed Systems Innovation (End-of-Year Celebration)
Join the Ray OSS community for our final meetup of 2025! As we close out a milestone year for distributed computing, we are bringing everyone together to review our collective progress and discuss what lies ahead.
"Ray: Last Year's Progress and the Road Ahead"
Speakers: Dhyey Shah, Ibrahim Rabbani
Following the deep dives presented at Ray Summit 2025, we will summarize the major advancements made in Ray’s performance, resiliency, and observability. We will also share a preview of the Ray Core 2026 roadmap and upcoming architectural enhancements.
"Structured Data Processing in Ray Data"
Speakers: Alexey Kudinkin
Ray Data is a data processing engine purpose-built for ML/AI workloads. In the past year, we've invested a lot in adding support for more traditional tabular data processing to Ray Data. In this talk, we'll discuss key new features like shuffles, joins, aggregations and columnar expressions; discuss new architectural changes needed to support these features; and showcase performance improvements that we see across Ray versions from these changes. We'll end with a discussion of future roadmap and case studies of Ray users successfully deploying Ray Data in production.
