Presto C++ in Action: Hands-on Benchmarking

Presto C++ is the next-generation Presto engine, built on Velox, an open-source, C++-based acceleration library for data processing. By replacing Java workers in Presto clusters with a native C++ execution engine, it delivers improved performance, reduced latency, and a modern architecture for analytics at scale.

In this workshop, we’ll walk through:

• Why Presto C++ was built and how it fits into the Presto ecosystem
• The architecture and performance benefits of a C++-based query engine
• The project’s current roadmap and how to get involved in the open-source community

Then we’ll get hands-on:

• Deploy Presto C++ locally with Docker
• Run and compare benchmarks against Presto Java using the open-source pbench tool
• Interpret the results and understand when to use each engine

By the end, you’ll know how to deploy Presto C++, run real benchmarks, and evaluate its performance for your workloads.

Course outline:

• Introduction & Overview of Presto C++
• Deploying a Presto C++ cluster with Docker
• Running Presto C++ vs Presto Java benchmarks with pbench
• Reviewing results and next steps
