Interesting. How does this compare to just generating generic system load (e.g. running some benchmark)?

- samokhvalov 6y agoWell, this tool is extremely useful when you want, for example, to test your monitoring system or other observability tools to understand how "bad" cases will be really visible in them. Of course, it should not be used in production. Also, it's a good idea to use it for training of DBA / DBRE / SRE engineers to practice various cases and improve their diagnostics skills. Regular benchmarks could have something like this embedded, I think. Postgres standard tool, pgbench, doesn't have it now. But I doubt "harmful workload" would be really useful when we test systems to see their max throughput / lowest latencies for particular workload.
