Amazon RDS now supports up to four storage modifications in 24 hours
Amazon RDS now allows up to four storage modifications per database instance within a rolling 24-hour window. These modifications let you increase the size, change the type, and adjust the performance of your RDS storage volumes. You can start a new modification right after storage optimization for the previous one completes, provided you have initiated fewer than four modifications in the past 24 hours.
This enhancement improves operational agility for scaling storage capacity or adjusting performance during sudden data growth or unexpected workload spikes. With RDS storage modifications, you can modify your volumes without downtime, keeping applications running with minimal performance impact.
The feature is available for all Amazon RDS engines in the Amazon Web Services China (Beijing) Region, operated by Sinnet and Amazon Web Services China (Ningxia) Region, operated by NWCD. It is automatically enabled without requiring workflow changes. To learn more about Amazon RDS storage, refer the Amazon RDS User Guide.
