Why Does the Number of Keys Decrease and Then Become Normal on the Monitoring Panel on the GUI of GeminiDB Redis API?

The number of keys is scanned and counted asynchronously by a GeminiDB Redis server to ensure final consistency. When an instance process is restarted (due to node restart, instance fault, specification change, or version upgrade), the keys are counted again. In this case, the number of keys displayed decreases temporarily and becomes accurate gradually.
