Amazon Web Services (AWS) Advanced Go Driver is generally available

The Amazon Web Services (AWS) Advanced Go Driver is now generally available for use with Amazon RDS and Amazon Aurora PostgreSQL and MySQL-compatible database clusters. This database driver provides support for faster switchover and failover times, Federated Authentication, and authentication with AWS Secrets Manager or AWS Identity and Access Management (IAM).

The Amazon Web Services (AWS) Advanced Go Driver "wraps" the pgx PostgreSQL driver or the native MySQL driver to provide enhanced functionality. You can install the PostgreSQL and MySQL packages for Windows, Mac, or Linux, by following the installation guides in GitHub. The driver relies on monitoring the database cluster status and being aware of the cluster topology to determine the new writer. This approach reduces writer failover times to single digit seconds compared to the open-source drivers on their own (pgx and native MySQL).

The driver is available as an open-source project under the Apache 2.0 license. For implementation details, please refer to the getting started instructions on GitHub.
