Java: Stop-The-World Pauses
Answer
By prioritizing regions with the most garbage first.
G1GC uses a heuristic approach to prioritize regions that contain the most reclaimable space, known as garbage-first collection. This strategy helps in efficiently reclaiming memory while minimizing pause times, crucial for high-availability services like streaming platforms during peak viewership times.
