🔗 ClickHouse adapter Elixir

Building an Ecto adapter for ClickHouse involved overcoming the limits of Postgres when handling aggregate data. The article describes how integrating ClickHouse's columnar storage improves query performance while preserving Ecto's familiar syntax and functions. The author shares insights on the development process, including utilizing a dependency-aware issue tracker called beads and employing a language model for incremental task breakdowns. An important aspect of the project was establishing a native TCP driver to facilitate efficient communication. Key challenges included debugging a complex handshake protocol and implementing a custom compression method. Ultimately, the project produced a functional clickhouse_adapter_ecto, enabling support for ClickHouse features while adapting them to Ecto's structure, proving the value of careful planning and incremental testing in software development.
