ClickHouse Over the Years with Benchmarks

ClickHouse is rapidly developing and adding new features such as semi-structured data support, asynchronous inserts, replicated database engine, RBAC, and others. The development team constantly improves performance and user experience. To compare the performance of different versions, a benchmark was run on an x86_64 AWS m5.8xlarge server with Ubuntu 20.04. The oldest available version used for the benchmark was ClickHouse 1.1.54378 from 2018. The results showed that ClickHouse is 28% faster than the older version. The development team has created a script to run common ClickHouse benchmarks on different hardware, which can be easily extended to add more queries.
