CompletableFutures allow parallel execution of tasks, reducing the total latency.
CompletableFuture is a tool that enables asynchronous programming in Java. By using CompletableFutures, you can execute multiple API calls in parallel, which reduces the overall time taken compared to executing them sequentially. For instance, querying inventory levels from multiple warehouses can be done concurrently, leading to faster response times for a customer placing an order.
