Getting started with benchmarking

Postgres FM

Michael and Nikolay are joined by Melanie Plageman, database internals engineer at Microsoft and major contributor and committer to PostgreSQL, to discuss getting started with benchmarking — how it differs for users and developers of Postgres, how and when it comes up during development, some tools and lessons, as well as what she's working on at the moment.
