Not a web dev - but have some experience in benchmarking these types of workloads e.g. https://www.mcobject.com/press/november19-2014/

L used the two open ones that are easy to replicate: H2O.ai (great bench) https://github.com/l-labs/db-benchmark TSBS (less great but useful) https://github.com/l-labs/tsbs

If there are others (will do ClickBench) they'll go there as well
