Why We Built InfluxDB 3's Query Engine on Apache DataFusion

May 26, 2026 | 8am PT | 4pm BST

Tomorrow we're going live with a deep dive into how DataFusion powers the query layer in InfluxDB 3, and there's still time to grab a spot.

If you've ever hit the wall with SQL dialects, custom file formats, or query performance at high cardinality, this one's for you. We'll show you how building on open source infrastructure (the FDAP stack: Flight, DataFusion, Arrow, Parquet) changes the game.

What's on the agenda:

  • Live technical demo: JOINs, aggregations, and high-cardinality workloads running on InfluxDB 3
  • Why vertically integrated databases create long-term pain — and what the alternative looks like
  • Recent DataFusion releases and what they mean for your query performance.
