Spring Boot @Async in Production: From Default Pitfalls to Thread Pool Governance

This article details Spring Boot @Async production pitfalls including unbounded thread creation, context loss, swallowed exceptions, and OOM risks, then provides concrete solutions: explicit ThreadPoolTaskExecutor configuration with bounded queues, TaskDecorator for MDC/TraceId/SecurityContext propagation, global exception handling, CompletableFuture orchestration without blocking, and monitoring with dynamic tuning to prevent thread leaks and OOM.

Why Does TraceId Get Mixed Up Under High Concurrency Even Though the Parent Thread Passes It to Child Threads?

The article explains why InheritableThreadLocal fails to propagate TraceId correctly in high‑concurrency thread‑pool scenarios, demonstrates the mixing problem with concrete request examples, and presents both manual propagation and Alibaba's TransmittableThreadLocal as reliable solutions.
