HAQM Relational Database Service (HAQM RDS) Multi-AZ deployments with two readable standbys now supports minor version upgrades and system maintenance updates with typically less than one second of downtime when using HAQM RDS Proxy. This capability allows you to take advantage of the most recent performance improvements, bug fixes, and any new security fixes or patches from the latest minor versions of PostgreSQL and MySQL with minimal interruption to your application.
Currently, minor version upgrades or system maintenance updates for HAQM RDS for PostgreSQL or MySQL databases can take several minutes and require planned downtime. Starting today, you can reduce downtime of minor version upgrades and system maintenance to 35 seconds or less using HAQM RDS Multi-AZ deployments with two readable standbys, and you can further reduce downtime to less than a second by including HAQM RDS Proxy. In a few clicks, you can add a managed, serverless HAQM RDS Proxy to your RDS Multi-AZ deployments with two readable standbys. In addition to HAQM RDS Proxy, you can also use the open source AWS Advanced JDBC Driver.
HAQM RDS Proxy is supported on all versions of HAQM RDS for PostgreSQL and MySQL available on RDS Multi-AZ Deployments with two readable standbys. For a full list of supported engine versions and regional availability, refer to the HAQM RDS User Guide.
