The Different Levels of Open Source

Alexey Milovidov, one of ClickHouse's creators, describes several levels of open-source engagement. From merely sharing code to active community engagement, ClickHouse has always aimed for the highest level of transparency and collaboration. This level, which includes clear contribution guidelines, task tracking, and an open release cycle, has been crucial for its widespread adoption.
