MySQL HeatWave now supports automatic recovery of loaded InnoDB tables from Storage Layer after a planned or unplanned restart of the primary DB system. This feature extends the existing functionality of automatic recovery from Storage Layer for Standalone DB systems to HA DB systems, thus reducing the recovery time, increasing the availability, and improving the overall system reliability. However, Lakehouse tables in HA DB systems still need to be recovered from Object Storage.
