Secondary Region
We are taking advantage of Amazon Aurora read replica write forwarding. With this feature enabled, writes can be sent to a read replica in a secondary region, and will be seamlessly forwarded to the writer in the primary region over a secure communication channel. It is considered a best practice to enable write forwarding in your secondary region for Warm Standby disaster recovery strategy for testing purposes.
