How Java Parallel Streams Work "Under the Hood"

This video examines how Java Parallel Streams work "under the hood," focusing on their implementation of a multi-core processor variant of the Map-Reduce paradigm. I provide a detailed analysis of the three-phase "Split-Apply-Combine" parallel stream approach. In the 'Split' phase, data is divided into atomic-sized chunks using spliterators. The 'Apply' phase processes these chunks concurrently in a common fork-join pool, utilizing work-stealing algorithms for efficiency. Finally, the 'Combine' phase aggregates the processed data into a single result through terminal operations like collect() and reduce(). I emphasize the efficiency gains achievable when using data structures that can be easily and evenly split.
