This architecture allows Fastify to efficiently process large numbers of concurrent requests. 1, 1, 2, 2, 3, 4
• Schema-Based Validation: Fastify supports schema-based validation, which means you can define a schema for your API requests and responses. This schema is used to validate the data received and sent, ensuring that the data conforms to the expected format. This validation process is often performed before and after data is sent or received, enhancing the overall reliability and performance of the application. 1, 1, 2, 2, 5, 6, 7
