For this demo, Materialize uses a custom benchmark called chBench that is really just a concatenation of two well-known database benchmarking tools, TPC-C and TPC-H.
TPC-C is an industry-standard benchmark for transactional workloads, meant to test a database’s scalability.
TPC-H is from the same group that developed TPC-C, and is meant to test the capabilities of online analytic platforms by performing complex analytic style queries. This includes large aggregations, many groupings, and complex multi-way joins.
CH-benCHmark brings together a TPC-C-like dataset with TPC-H’s analytical queries. This is a great approximation for how many businesses perform OLAP queries over OLTP data.
大意是说，TPC-C 能产生一个数据集，并产生重事务的大量请求。TPC-H 能产生大量复杂查询的请求。CH-benCHmark 将两者整合。
