When considering autoscaling for provisioned throughput in NoSQL Database Cloud Service, which metric is LEAST relevant for determining when to scale up the capacity units?
A . CPU utilization of the compute instances hosting the database:
Autoscaling in NoSQL Database Cloud Service primarily focuses on RCUs (Read Capacity Units) and WCUs (Write Capacity Units).
The objective is to dynamically adjust capacity based on query workload, not on CPU utilization.
Even if CPU usage is high, it might not necessarily indicate that the capacity units are inadequate.
Why the other options are more relevant:
B . Rejected read requests (RCUs): Direct indicator that read capacity is insufficient, requiring scaling.
C . Rejected write requests (WCUs): Indicates that the write throughput is inadequate, necessitating scaling.
D . Latency of read and write operations: Increased latency often points to under-provisioned throughput.
