Memory Management & Reducing GC Pressure
Understand JVM garbage collection and learn concrete Clojure techniques to cut allocations and reduce GC pauses in hot code paths.
Why GC Matters
The JVM automatically reclaims unused memory through garbage collection. But GC pauses can hurt latency. Reducing allocations means less GC work and smoother performance.
Generational Heap
The JVM heap is split into generations. Most objects die young, so the young generation is collected often and cheaply; survivors move to the old generation.
