Why Does JVM Heap Memory Usage of JVM Fluctuate Significantly?

It is normal that JVM Heap Memory Usage of JVM is displayed in a sawtooth shape on the monitoring page. The maximum value may further increase or the fluctuation may be greater after scale-out or an engine upgrade. Such fluctuations are caused by normal JVM heap memory reclamation, and do not affect services.
