Answers use simple, clear English.
Quick interview answer
Compare Virtual Threads (Project Loom) vs the usual alternative on complexity, latency, failure modes, and ops cost. Pros: Simpler than reactive stacks for IO-bound code; familiar thread model. Cons: Pinning with synchronized/native/JDBC drivers still possible; not for CPU-bou…
Detailed answer
Design-review comparison for Virtual Threads (Project Loom): Axes: correctness, latency, throughput, complexity, operability. From the topic: Pros: Simpler than reactive stacks for IO-bound code; familiar thread model. Cons: Pinning with synchronized/native/JDBC drivers still possible; not for CPU-bound. Recommendation: pick Virtual Threads (Project Loom) when its strengths match the SLO; otherwise choose the alternative and say why. Parent context: Baseline: Virtual threads are lightweight; block on IO without pinning platform thread (mostly). Executors.newVirtualThreadPerTaskExecutor() simplifies massive concurrency.
