  https://cloud.google.com/spanner/docs/instance-configurations#multi-region-best-practices Best practices For optimal performance, follow these best practices:

  Design a schema that prevents hotspots and other performance issues. For optimal write latency, place compute resources for write-heavy workloads within or close to the default leader region. For optimal read performance outside of the default leader region, use staleness of at least 15 seconds. To avoid single-region dependency for your workloads, place critical compute resources in at least two regions. A good option is to place them next to the two different read-write regions so that any single region outage will not impact all of your application. Provision enough compute capacity to keep high priority total CPU utilization under 45% in each region.

• D: Keep the total CPU utilization under 45% in each region. For optimal performance, follow these best practices: • Design a schema that prevents hotspots and other performance issues. • Place critical compute resources within the same region as your Spanner instance. • Provision enough compute capacity to keep high priority total CPU utilization ***** under 65%.
