Presto Cost-Based Optimizer rocks the TPC benchmarks!

As mentioned in our previous blog about the Starburst Presto release and its hottest addition – the Cost Based Optimizer for Presto we’re happy to share the results of benchmarks we did for this release (195e) comparing it to the ‘vanilla’ Presto release 195. Now we will continue on the process of getting all those CBO-related changes merged into the ‘vanilla’ Presto repository.

The benchmarks were performed using a standard set of TPC-H and TPC-DS queries. As a side-note, I would like to highlight that, thanks to our team’s contributions throughout the last couple years, Presto supports 100% TPC benchmark queries and executes them unmodified! That is with no prohibited query modifications. You can find the queries in our repository.
