How Long Does It Take to Create a DB Instance?
Generally, creating a DB instance (single or primary/standby) takes 5 to 7 minutes. The time required for creating a read replica depends on the data amount of the primary DB instance. A larger data amount indicates a longer read replica creation time. If the primary DB instance is empty, creating a read replica takes 7 to 8 minutes.
If the duration is exceeded, a fault may occur during the creation. Please contact customer service.
