Focus: Stop-The-World Pauses
Java: Stop-The-World Pauses
Answer
A comprehensive cleaning of the entire heap.
A full GC is a garbage collection event that cleans the entire heap, including both young and old generations. This process can lead to longer 'Stop-The-World' pauses as it involves extensive memory compaction and deallocation. For example, in a heavily trafficked web service, frequent full GCs could cause periodic slowdowns.
