Amazon RDS supports four storage modifications daily
🔧 Amazon RDS now permits up to four storage modifications per database instance within a rolling 24-hour window. These changes let you increase size, change volume type, and adjust performance without incurring downtime, and a new modification can begin once the previous optimization completes. The feature is automatically enabled across Amazon RDS for PostgreSQL, MariaDB, MySQL, Db2, Oracle, and SQL Server in all commercial AWS Regions and AWS GovCloud (US).
