No one likes benchmarking. But it can be one of the highest impact things you do. Jelte Fennema-Nio and Marco Slot joined Claire Giordano and Pino de Candia on this episode of Path To Citus Con* podcast for developers who love Postgres—to discuss their journeys into performance benchmarking. And how it can change the course of your career. Do you need to find bottlenecks in your Postgres? Do you want to build skills with database benchmarks? There are many lovely benchmarking tools in the Postgres world: HammerDB, pgbench, YCSB, BenchBase, perf, & more. And in addition to running benchmarks themselves—asking the right questions, introspection, and profiling matter just as much.
*[Update: July 2024] Path To Citus Con has been renamed to Talking Postgres. All of the past podcast episodes from Path To Citus Con—now called Talking Postgres with Claire Giordano—can be found here: https://talkingpostgres.com
