HOW PINTEREST STORES AND TRANSFERS HUNDREDS OF TERABYTES OF DATA DAILY

Summary from the TLDR Web Dev newsletter

Pinterest's engineering team developed a Change Data Capture (CDC) system to manage the hundreds of terabytes of data its platform processes daily. This system, built using Debezium, addresses the challenges of real-time data processing for personalized recommendations and fraud detection. The architecture includes a control plane for managing connectors and a data plane that uses Kafka to transfer change events from distributed databases.
