Hi there 👋

I'm Andy Grove, a software engineer specializing in distributed systems and query engines. I am the author of the book How Query Engines Work.

Work

I work for NVIDIA where I contribute to the RAPIDS Accelerator for Apache Spark, which is an open source plugin that provides GPU-acceleration for ETL workloads, leveraging the RAPIDS cuDF GPU DataFrame library.

Open Source

  • I am a PMC member of Apache Arrow, where I donated the initial Rust implementation and later donated the DataFusion query engine.
  • I believe that Rust and Apache Arrow together provide a great foundation for distributed systems and I created the Ballista Distributed Compute platform to demonstrate the possibilities.

Hobbies

I occasionally work on hobby projects involving digital electronics, microcontrollers, woodworking, and similar skills. Some of my projects have been featured on popular "maker" web sites.

Detect task failures in benchmarks

This is a breaking change to the JSON reporting of query times. Previously, the queryTime field would contain -1 if the query failed and >= 0 if th…
