OCI Cache Best Practices

Follow these best practices for working with clusters in OCI Cache.

Stop writing data to a cluster when memory is close to full

Don't continue to write data to a cluster when the cluster's available memory utilization is greater than 85%. Continuing to write data in this scenario can cause the cluster to fail. To avoid this scenario, configure metrics and alarms on memory usage for a cluster so that you're notified when a cluster's available memory is close to full. The applicable metric is MemoryUtilization, defined in Available Metrics.

When the alarm indicating that the memory usage threshold has been breached is triggered, resize the memory for the cluster to increase the available memory. For example, you can configure the alarm to trigger when MemoryUtilization is 70%, 75%, or 80%.
