The storage space allocated to your Amazon Aurora database cluster will now dynamically decrease when you delete data from the cluster. The storage space already automatically increases up to a maximum size of 128 tebibytes (TiB), and will now automatically decrease when data is deleted. You only pay for the storage you use. Starting September 21, 2020, dynamic resizing for storage space is being enabled region by region for Aurora MySQL versions 1.23 and 2.09, and Aurora PostgreSQL versions 10.13 and 11.8, and is expected to be enabled across all Aurora regions by end of November 2020. 

Previously, when you deleted data from Aurora clusters, such as by dropping a table or partition, the overall allocated storage space remained the same. This was because the free space was not released in order to be reused automatically if data was added later. With dynamic resizing, the allocated storage space decreases automatically when you delete data. Learn more by visiting the Amazon Aurora Storage and Reliability documentation.
