Adyen, a global fintech company renowned for its seamless payment processing services, has successfully transitioned its online payment system to CockroachDB, enhancing their ability to handle increased transaction volumes without downtime. Established in 2006 in Amsterdam, Adyen has evolved from a payments company to a comprehensive tech platform, offering solutions like embedded finance, risk management, and data analysis. The company faced challenges with their previous PostgreSQL setup due to necessary downtimes and the complexity of achieving idempotency. CockroachDB, being PostgreSQL wire-compatible, facilitated a smooth migration while offering distributed data capabilities that ensure transactions are not double-processed. This transition has allowed Adyen to maintain uptime and consistency across its global operations, with CockroachDB's distributed nature enabling reads and writes from multiple locations. As Adyen continues to innovate, they are exploring new use cases for CockroachDB, including customer loyalty applications and a CockroachDB-as-a-Service model.
