Amazon Aurora Global Database for PostgreSQL now lets you forward write requests from a secondary to a primary Region, simplifying writing from multiple Regions and making it easier to develop globally distributed applications. With this launch, write forwarding is now available on both Aurora Global Database for MySQL and PostgreSQL.

Amazon Aurora Global Database allows a single Aurora database to span multiple Amazon Web Services Regions, providing disaster recovery from Region-wide outages and enabling fast local reads for globally distributed applications. With write forwarding, your applications can simply send both read and write requests to a reader in a secondary Region, and Global Database will take care of forwarding the write requests to the writer in the primary Region. You can also use different consistency levels that meet your application needs. Global Database write forwarding is supported on Aurora MySQL versions 2.08.1 or higher, and Aurora PostgreSQL versions 14.9, 15.4, or higher. You can enable the feature using the Amazon Web Services Management Console, Command Line Interface (CLI), or RDS API by turning on the "enable global write forwarding" option. The feature is available in all Amazon Web Services regions where Aurora Global Database for PostgreSQL is available, including the Amazon Web Services China (Beijing) Region, operated by Sinnet and the Amazon Web Services China (Ningxia) Region, operated by NWCD.
