In Kubernetes, fast read and write operations are important to ensure high performance and reliability of the cluster. They are necessary for:

• Ensuring the currency of the state: Kubernetes components often access the API server to read and update the state of objects (Pods, Services, etc.). Fast operations allow quick response to changes.
• Data consistency: during scaling, updates, and recovery, it is important to quickly write new data and read current data to avoid inconsistencies.
• Supporting high load: in large clusters with many objects and requests, operation latencies should be minimal for stable operation.

For example, Kubernetes controllers constantly read the state of objects and record changes to maintain the desired system state. If operations are slow, this will lead to delays in responding to events and deterioration of application performance.
