The AWS JDBC Driver for PostgreSQL is now generally available for use with your Amazon RDS or Amazon Aurora PostgreSQL-compatible edition database clusters. This wrapper driver is designed to work with the PostgreSQL community driver and provide improved failover handling for clustered databases such as Aurora PostgreSQL. The AWS JDBC Driver for PostgreSQL is drop-in compatible with your existing applications because it adds failover functionality alongside the community driver, reducing the need for you to make application changes. This release replaces the standalone AWS JDBC Driver for PostgreSQL previously released as a preview.
The wrapper driver minimizes failover time by monitoring database cluster status and caching the cluster’s topology. The cache is then used to improve DNS name resolution speed if a node fails, reducing failover time from minutes to seconds. It is an open-source project that uses the Apache License v2 and can be installed using Maven, Gradle, or by .jar file.
The AWS JDBC Driver for PostgreSQL supports IAM database authentication. Visit the project in GitHub to download the driver and open feature requests.
