Mastering HarmonyOS Concurrency: TaskPool, Worker & TaskGroup in AI Photo App

Through an AI ID photo tool case study, this article demonstrates HarmonyOS concurrency patterns: TaskPool for short preprocessing, Worker for long AI inference, TaskGroup for parallel batch generation, SequenceRunner for dependent tasks, SharedArrayBuffer for zero-copy sharing, Sendable for thread-safe singletons, and producer-consumer queues for real-time previews, with before/after performance metrics.
