How Convex Works

Convex is a backend platform that offers a unique approach to database management by seamlessly integrating client-defined API functions as transactions within a cloud-based environment. By utilizing a transaction log, Convex maintains a strong consistency and high transaction throughput, ensuring that operations such as adding items to a shopping cart are executed atomically to prevent inconsistencies like race conditions. The platform employs optimistic concurrency control to allow parallel transaction execution while ensuring serializability, meaning that operations behave as if executed one at a time even in a concurrent setting. Convex also supports real-time updates through subscriptions, where read sets from executed queries are monitored for changes, enabling automatic updates to the client when data modifications occur. The system is designed to cater to both early-stage development ease and later-stage robustness, allowing developers to benefit from a schemaless model while also providing schema-driven capabilities. With its sync engine at the core, Convex offers a comprehensive solution for scalable full-stack AI projects, integrating cloud functions, a database, file storage, and real-time updates in a cohesive manner.
