Answer
Metaspace is a memory area in the JVM for class metadata.
Metaspace stores class definitions, method metadata, and other class-related data. Unlike the old PermGen, Metaspace grows dynamically and is not limited by the heap size. For instance, in a Spring application that generates many dynamic proxies, Metaspace handles the class metadata efficiently, preventing out-of-memory issues that were common with PermGen.
