Growth Book now natively supports ClickHouse as a data source for experiment data. ClickHouse is a popular open source data warehouse/OLAP (Online Analytical Processing) that scales massively, and is behind Yandex.Metrica. Users of ClickHouse can now easily run A/B tests with this data by using Growth Book. Simply add a new data source, select ClickHouse from the drop down list, and add your connection details.
Once the data source is defined, you can use it to create metrics you want to test against. Happy experimenting.
