Amazon Aurora PostgreSQL now supports local write forwarding
Amazon Aurora PostgreSQL-Compatible Edition now lets you forward write requests from Aurora read replicas to the writer instance, simplifying scaling read workloads that require read-after-write consistency. With this launch, local write forwarding is now available for both Aurora MySQL and Aurora PostgreSQL.
With write forwarding, your applications can simply send both read and write requests to a read replica, and Aurora will take care of forwarding the write requests to the writer instance in your cluster. This way your applications can scale read workloads on Aurora Replicas without the need to maintain complex application logic to separates reads from writes. You can also select from different consistency levels to meet your application read-after-write consistency needs. Local write forwarding is supported on Aurora PostgreSQL versions 14.13, 15.8, 16.4 or higher. You can enable the feature using the AWS Management Console, Command Line Interface (CLI), or API by turning on the "local write forwarding" option. See our documentation to learn more.
