Data Mesh: How Netflix moves and processes data from CockroachDB

Netflix employs a sophisticated data mesh architecture to manage and process data from various operational data stores, including CockroachDB, MySQL, Postgres, and Cassandra, to deliver real-time insights and improve user experiences. The data mesh facilitates decentralized data architecture, allowing data to be extracted and processed through pipelines that enable transformation and enrichment before reaching its final destination, such as a data warehouse or search index. A critical component of this system is the CockroachDB CDC connector, which addresses challenges like data format translation, schema change handling, backfill management, and event ordering to ensure seamless data flow. This architecture supports Netflix's need for scalable, real-time data processing and decision-making capabilities, highlighting the importance of event-driven systems in optimizing business operations and enhancing user experiences.
