Understanding Java's Asynchronous Journey
Connect with me Understanding Java’s Asynchronous Journey A walk-through of the evolution and explanation of concurrent programming in Java, from the early days of Threads in Java 1 to the StructuredTaskScope in Java 21. Asynchronous programming skills are no longer “nice-to-have”; almost every programming language has it and uses it.
If you remember the problem we discussed with Future.get(), which was blocking the asynchronous task post its invocation, CompletableFuture prevents it by providing a chaining of operations on the received data. Think of Kafka or any other message queues that process large quantities of data, where the need for concurrency with excellent resource utilisation is of paramount importance. 👉 Similar to completable futures, these too are non-blocking in nature, and you can safely block the tasks like I/O operations without leading to thread starvation.
