Reading and Writing JFR Files Programmatically - Mostly nerdless

A practical guide to reading and writing JFR (Java Flight Recorder) files programmatically using three approaches: Java's built-in RecordingFile API, the jafar library by Jaroslav Bachorik (which uses compile-time code generation for speed and low memory footprint), and the JMC JFR writer API for creating custom JFR files. The post also introduces basic-jfr-processor, a new library built on top of the JMC writer API that simplifies modifying existing JFR files, such as dropping or altering specific event types.
