Is your Blocking Queue... Blocking?

Read Original

This technical article explores how to detect when producer threads are blocked on a Java BlockingQueue, a common performance bottleneck. It discusses using JDK Flight Recorder (JFR) and custom event emission for real-time analysis in production, as traditional profilers may not be available. The post includes a practical example using SQLite and batch processing to improve write throughput.
