How does a Subscriber request data in Reactive Streams?
Track: Java
Topic: Reactive Streams
Focus: Publisher and Subscriber
Java: Publisher and Subscriber
Answer
A Subscriber requests data using the request(n) method.
In Reactive Streams, a Subscriber signals its demand for data by calling request(n) on the Subscription. This controls backpressure, ensuring the Publisher only sends as much data as the Subscriber can handle. For instance, a logging system might request 10 records at a time for processing, preventing overload.
