Cost-based optimizer in Presto

less than 1 minute read

The multiyear effort started at Teradata and continued at Starburst is getting close to its final shape. Even though it is in the initial version of cost-based optimizer we were able to see really nice speedups in TPCH and TPCDS benchmarks (up to 10-15x). It is a great foundation for more optimizations in the future. I can’t wait to see it working at production and to get first feedback from Presto users.

I know you are all waiting for some implementation details. So here there are. Below are the links to post series from Starburst blog written by my friends and me.

Cost-based optimizer will be released in Starburst’s 195e and Teradata’s 195t. It is hard to tell when it will appear in vanilla Presto release, it is on going process.
