ClickHouse Review

In 2018 I downloaded clickhouse and although tricky to setup at the time, once I got it up and running the ability to store and years of tick data including ASOF joins was something no other open source database supported at the time. Since then it's got friendlier, more features and even faster.

ClickHouse has the most open and comprehensive benchmarking suite of any database we have seen and we've looked at a lot of benchmarks.

If you want a more in depth look at ClickHouse in finance, I recommend ClickHouse at Deutsche Bank by .
