Velox

#VeloxCon 2026 recordings are now posted 👏 catch everything you missed. This year's event brought together hundreds of the Velox community in-person, with over 2K combined livestream views across both days. The energy in the room matched the momentum we're seeing across the Velox ecosystem 🚀 Sessions covered the latest in Velox development, real-world deployments, and what's coming next from contributors across the community. Whether you were there or tuning in from across the world, the full playlist is now available. Stay tuned for our next community event 👀 https://lnkd.in/giKHKVCz

Day 2 of #VeloxCon is LIVE in 30 minutes 🔥 If you couldn’t join us yesterday (or want more), we’ve got you - tune in to the Day 2 livestream from anywhere 👍 More talks today from engineers at Nvidia, Meta, Oracle and more. Jump in, catch a session, and see what’s happening across the ecosystem. Watch here → https://lnkd.in/gCvwbtZn

Big news - we’ll be LIVE at #VeloxCon starting in 30 minutes 🔥 If you're not able to join us in-person, we're happy to share the VeloxCon livestream - tune in from anywhere 👍 If you’re into execution engines, data infra, or how systems like Velox are powering modern analytics + AI workloads, come join us. Talks all day from engineers at Meta, IBM, Microsoft and more. Watch here → https://lnkd.in/gAr9e5Qw

⭐ #VeloxCon Keynote Spotlight ⭐ VeloxCon starts tomorrow! Join Maria Basmanova from Meta who will share the vision and architecture behind Axiom, Meta’s next-generation compute platform. She'll cover how it builds on Velox and the design principles shaping future execution engines. Last chance to grab a seat! Hope to see you there. 📅 April 29-30, 2026 📍 Meta HQ, Menlo Park https://veloxcon.io/

Migrating UDFs to Velox can be slow and manual, unless you automate it. In this lightning talk at #VeloxCon, Miaojiang (MJ) Deng and Sandeep Thandassery from Meta will share a workflow where an AI agent generates C++ UDFs and validates them with differential fuzz testing against the original Java versions. The result: significantly faster migration with high confidence in correctness. We hope to see you TOMORROW! 📅 April 29-30, 2026 📍 Meta HQ, Menlo Park https://veloxcon.io/

Bringing iteration into Velox 🔍 learn more at #VeloxCon Zhichen Xu, Ph.D., Junjie Q. and Jingfang Liu from Meta will explore how Velox can support iterative computation for workloads like clustering, graph processing, and agent pipelines. They’ll walk through how existing primitives (exchange, aggregation, vector ops) could be composed into iterative workflows, along with the challenges around coordination and state. Join us for a deeper look at how execution engines may evolve. 📅 April 29-30, 2026 📍 Meta HQ, Menlo Park https://veloxcon.io/

💡 Making open source contribution loops faster (and less painful) At #VeloxCon, Krishna Pai (Meta) will share how the Velox CI pipeline is being rethought with faster feedback, cleaner signal, and AI built directly into the workflow. What’s changed: - CI feedback in minutes instead of hours - Better handling of flaky tests and clearer failure reports - LLMs reviewing PRs and explaining CI failures in plain English A practical look at how AI is improving the day-to-day experience of contributing to open source. 📅 April 29-30, 2026 📍 Meta HQ, Menlo Park https://veloxcon.io/

👉 Bringing Presto, Spark, and Velox together At #VeloxCon, Shrinidhi Joshi (Meta) will take a deep dive into Project Sapphire (Presto-on-Spark) - a C++-based Presto engine running on Spark with Velox execution. The session covers how Sapphire extends Velox in key areas: - Shuffle integration tightly coupled with memory and serialization - Broadcast joins with reusable hash tables - Sorted shuffle and sort-merge join support Along with real production results showing performance gains over Presto’s Java engine. Join us! 📅 April 29-30, 2026 📍 Meta HQ, Menlo Park https://veloxcon.io/

#VeloxCon is where graph, vector search, and SQL come together. In this lightning talk, Abdullah Ozturk and Vishal Gandhi from Meta will show how they built a Cypher-based query layer on Velox to run queries across graph stores, databases, and search systems. By mapping graph patterns to relational operations, they reuse Velox for execution and enable hybrid RAG workflows (vector + text + graph) in a single query. Excited to see more details! 📅 April 29-30, 2026 📍 Meta HQ, Menlo Park https://veloxcon.io/

#VeloxCon Session Spotlight: Velox IO - Nimble Index & Open Table Formats Xiaoxuan M. (Meta) will share recent work on the Velox IO layer, focused on improving how data is stored, indexed, and accessed. That work includes: - A Nimble serializer for more efficient SST file encoding - Cluster keys and dense indexing for faster data access - Extending Velox connectors to support #Iceberg and #Paimon A great session if you’re thinking about storage formats, ingestion performance, and interoperability across the lakehouse ecosystem. 📅 April 29-30, 2026 📍 Meta HQ, Menlo Park https://veloxcon.io/
