Starting today, Amazon Aurora MySQL includes optimizations that reduce the database restart time by up to 65% versus without optimizations. These improvements are achieved by deferring portions of the buffer pool initialization and validation process to occur after the database is already online and accepting connections. These optimizations will improve database availability for unplanned events such as unexpected database restarts and planned operations such as minor version upgrades. To learn more about availability benefits, you can refer to our blog titled ‘Reduce downtime with Amazon Aurora MySQL database restart time optimizations’.

These optimizations are enabled by default on Aurora MySQL versions 3.05 and higher and are available in all AWS regions where Aurora MySQL is available. Please review the Aurora documentation to learn more.

Amazon Aurora is designed for unparalleled high performance and availability at global scale with full MySQL and PostgreSQL compatibility. It provides built-in security, continuous backups, serverless compute, up to 15 read replicas, automated multi-Region replication, and integrations with other AWS services.
