Materialize, an operational data warehouse, enhances its speed and correctness by transitioning its high-speed data processing to a cloud-based architecture, leveraging CockroachDB for scalability and managed services. Originally built on open-source frameworks Timely Dataflow and Differential Dataflow, Materialize offers real-time data streaming with sub-second latency, aiming to overcome traditional data warehouses' limitations. To meet its requirements for high availability and rapid query response times, Materialize evaluated several databases, ultimately selecting CockroachDB due to its managed solution and scalability, which aligns with their goal of reducing operational burdens. The collaboration with Cockroach Labs has been fruitful, marked by responsive communication and tailored feature additions, ensuring Materialize's needs are met efficiently.
