Memory Management & GC Tuning
Deep dive into JVM memory management, garbage collection, and techniques for optimizing memory usage in Scala.
JVM Memory & GC Intro
Welcome! In this lesson, we'll dive into how the Java Virtual Machine (JVM) manages memory, especially crucial for Scala applications.
- Understanding memory helps you write efficient, performant code.
- We'll explore Garbage Collection (GC), the JVM's automatic memory manager.
- Proper memory management prevents common issues like 'out of memory' errors.
The Heap: Object Storage
The Heap is the largest memory area in the JVM, where all objects created by your Scala application reside. This includes instances of classes, arrays, and most data structures.
The Heap is shared across all threads in your application. Its size directly impacts how many objects your program can hold simultaneously.
