It reported median steady-state write-round speedups of 5.5× and 4.7×, respectively. The result is a useful signal about storage-aware execution, but it is not evidence that all Spark queries—or production workloads—will see the same gains.","published_at":"2026-11-06","updated_at":"2026-11-06","record_date":"2026-11-06","date_kind":"published_at","topics":["compute","infrastructure"],"entities":["Uber","Apache Spark","Onehouse Quanton","Apache Hudi","Apache Gluten","Velox","Drogon"],"related_patterns":[],"novelty_label":"new_fact","what_changed":"Uber reports Spark performance and cost gains from Apache Gluten and Velox, and describes benchmarking Onehouse Quanton.","prior_refs":[],"source_url":"https://www.uber.com/us/en/blog/uber-benchmarking-quanton","source_urls":["https://www.uber.com/us/en/blog/uber-benchmarking-quanton"],"schema_version":"newruntime-agent-readable-v0.2","stable_id":"post:making-every-core-count-in-pursuit-of-faster-996a1b","status":"published","visuals":[],"editor":{"role":"editor","name":"Andrey Reshetnikov","profile":"https://newruntime.com/owner-profile.md","profile_json":"https://newruntime.com/owner-profile.json","same_as":["https://www.linkedin.com/in/reshetnikov1/","https://t.me/lapetuse"]},"routes":{"html":"https://newruntime.com/posts/making-every-core-count-in-pursuit-of-faster-996a1b/","markdown":"https://newruntime.com/posts/making-every-core-count-in-pursuit-of-faster-996a1b.md","json":"https://newruntime.com/posts/making-every-core-count-in-pursuit-of-faster-996a1b.json"},"markdown_url":"https://newruntime.com/posts/making-every-core-count-in-pursuit-of-faster-996a1b.md","next_reads":[{"type":"topic","path":"/topics/compute/","url":"https://newruntime.com/topics/compute/","title":"Compute","reason":"Explore the compute topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/compute.md","json_url":"https://newruntime.com/topics/compute.json"},{"type":"topic","path":"/topics/infrastructure/","url":"https://newruntime.com/topics/infrastructure/","title":"Infrastructure","reason":"Explore the infrastructure topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/infrastructure.md","json_url":"https://newruntime.com/topics/infrastructure.json"},{"type":"collection","path":"/posts/","url":"https://newruntime.com/posts/","title":"Field Notes","reason":"Open the latest editorial analysis.","media_type":"text/html","json_url":"https://newruntime.com/posts.json"},{"type":"collection","path":"/sources/","url":"https://newruntime.com/sources/","title":"Sources","reason":"See the original sources this archive cites.","media_type":"text/html"}]}
