Amazon Aurora PostgreSQL now supports local write forwarding
News
Amazon Aurora PostgreSQL-Compatible Edition now supports local write forwarding, allowing write requests from Aurora read replicas to be forwarded to the writer instance. This simplifies scaling read workloads that require read-after-write consistency.
Specifically, the article covers:
- With write forwarding, applications can send both read and write requests to a read replica, and Aurora will forward the write requests to the writer instance in the cluster.
- This allows scaling read workloads on Aurora Replicas without complex application logic to separate reads from writes.
- Different consistency levels can be selected to meet application read-after-write consistency needs.
- Local write forwarding is supported on Aurora PostgreSQL versions 14.13, 15.8, 16.4 or higher, and can be enabled using the AWS Management Console, CLI, or API.
- Amazon Aurora combines the performance and availability of commercial databases with the simplicity and cost-effectiveness of open-source databases.
