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 Amazon Web Services regions with Aurora MySQL, including Amazon Web Services China (Beijing) Region, operated by Sinnet and Amazon Web Services China (Ningxia) Region, operated by NWCD.
