Video: Supercharge Your Full-stack App with a Reactive Database

Convex is a sync engine that includes a database, file storage, vector embeddings, full text search, and more. It is written in Rust and can be hosted on the Convex platform or self-hosted as it is open source.

Convex simplifies the development process by allowing developers to write code that gets automatically compiled and deployed. It manages caching and state synchronization via WebSockets, reducing the need for manual infrastructure management and decision-making.

Convex is built from the ground up with 200,000 lines of Rust and operates using V8 isolates for running code alongside data. It integrates seamlessly with React, TypeScript, and other languages through its clients.

Convex uses WebSockets to sync data in real-time. When underlying data changes, all clients subscribed to the data receive instant updates, ensuring seamless real-time data synchronization.

Convex provides three main functions to interact with: Actions (arbitrary code execution), Queries (data retrieval), and Mutations (data writing). These functions allow developers to efficiently manage and interact with their data.

Convex manages scalability through dynamic resource allocation and load balancing across multiple instances, allowing it to handle thousands of concurrent WebSocket connections efficiently.

Convex for Startups offers perks like free access to Convex, founder Q&As, and code walkthroughs. It is designed to support innovative and novel startup projects using Convex.

Yes, developers can enforce schema validation in Convex to ensure data integrity. Convex supports complex queries, indexes, and relationships between tables, providing flexibility and performance.

Yes, Convex is designed to be effortlessly scalable, handling large-scale applications and complex distributed systems challenges, though it's currently more suited for scaling up existing projects rather than onboarding large enterprises immediately.

Convex's database is custom-built in Rust, not reliant on traditional systems like Postgres or MySQL. It is designed specifically to handle distributed systems efficiently, leveraging the expertise of its founders who previously built Dropbox Sync.
