Reactive MongoDB

Reactive MongoDB with Spring Data MongoDB allows for nonblocking, event-driven programming with MongoDB. We can build highly scalable and responsive applications by leveraging reactive streams and the MongoDB reactive driver. Reactive MongoDB enables efficient handling of asynchronous data streams and supports reactive features like backpressure and concurrency, enhancing performance and responsiveness.

One example of why we should use reactive programming through Spring Data MongoDB is to handle high-concurrency scenarios or applications that require nonblocking I/O, where responsiveness and scalability are critical. Consider an e-commerce application that needs to handle a high volume of concurrent requests for product information. When a user requests product details, the application can fetch data from MongoDB and respond promptly without blocking resources.
