Darwinium has chosen ClickHouse as its database engine due to its ability to simplify data pipelines, handle high-throughput writes and analytics of complex data types. ClickHouse's support for mutable engines, map and array data structures, and JSON type support make it an ideal choice for Darwinium's use cases. The platform can process a few thousand writes per second, with multiple data pipeline writers writing to a single server, and has consistent low CPU core readings. Additionally, ClickHouse supports cloud-native deployment, cost-aware storage patterns, and distributed and highly available architecture, making it well-suited for fraud and security domain use cases. The platform's rich function catalogue, SQL interface, and ability to deploy and run on various hardware configurations also make it a compelling choice.
