The [SynchronizedSpliterator](https://github.com/apache/ozone/pull/8203#issuecomment-2932317879) approach is inefficient -- Spliterator is designed to split a collection into multiple parts and then iterate the individual parts in parallel. For example, suppose there is a list with 10,000,000 elements and it is going to be processed by 100 threads. - Spliterator is designed to do the split first, say splitting it into 1000 parts with 10,000 elements each. Then, the 100 threads only have to be synchronized 1000 times for picking up the individual parts. - For SynchronizedSpliterator, since it has synchronized at tryAdvance(..), the 100 threads have to be synchronized 10,000,000 times for picking up the individual elements. -- This is an automated message from the Apache Git Service.
