ClickHouse Performance Benchmarking – Brown University

Brown University Benchmark on ClickHouse

At ChistaDATA, We work for some of the largest ClickHouse installation worldwide and performance is very critical for our customers and ChistaDATA is committed to delivering optimal ClickHouse operations to the clients globally. ChistaDATA provides/publishes ClickHouse Application performance. We publish data of  both hardware and software infrastructure used for benchmarking ClickHouse with GitHub / data if ever needed to reproduce the same. The performance metrics published covers both Average Response Time / Latency and Throughput. We strongly believe that it’s the responsibility of ClickHouse infrastructure stakeholders / DBAs / Data SREs / Performance Engineers to understand the thresholds of their ClickHouse operations which eventually depend on RAM, CPU, Disk performance and Network latency. The key to ClickHouse performance benchmarking is to deliver consistently reproducible results. This is really important because the reproducible results allows you to rerun the tests and also gain confidence in the overall ClickHouse performance benchmarking exercise.
