Virtual Threads Eliminated Thread Pools — Until MySQL Connections Ran Out

After upgrading to Java 25 and Spring Boot 4, the author enabled virtual threads and removed custom thread pools for IO-heavy aggregation endpoints. While code simplified dramatically, the bottleneck shifted from thread exhaustion to HikariCP connection pool exhaustion, revealing that virtual threads don't increase downstream capacity. The solution: limit scarce resources (DB connections, HTTP clients) directly rather than limiting threads.

Handling Data Surge in a Data Push Platform: JVM Tuning, Flow Control, and Performance Optimization

This article analyzes the challenges of data‑burst scenarios in a data‑push platform, evaluates traditional throttling methods, presents JVM‑level tuning and a custom heap‑usage based flow‑control mechanism, and validates the solution through extensive pressure testing, demonstrating significant reductions in full GC frequency and overall push latency.
