Java Parallel Streams Internals: Order of Results for Aggregate Operations

This video discusses the intricacies of aggregate operations in Java Parallel Streams, focusing on how these operations affect result ordering. It highlights that intermediate operations like sorted(), unordered(), skip(), and limit() influence the ordering, with distinct() and limit() being stateful and potentially slowing down execution. The video also explores terminal operations, contrasting forEachOrdered(), which ensures order and includes implicit synchronization, with forEach(), which might be faster but doesn't guarantee order. Despite these complexities, I recommend using terminal operations that produce a result, as they provide cleaner code and handle concurrency issues automatically.
