Unable to create RDS instance with 1GB allocated storage

Question

hi, i found that the minimum allocated storage while creating an RDS instance is set to 20GB. However, I have a use case which only need a few MB of DB storage size. Can anyone advise me on how to create a RDS instance (MySQL db) with just 1GB storage? 
Thank you.

Answer

yep, you can't create a RDS MySQL provision storage less than 20 GB. please check the doc(https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/CHAP_Storage.html)

btw: you can use aurora serverless v2 for MySQL, then you can pay for using storage. Amazon Aurora Serverless v2 is suitable for the most demanding, highly variable workloads.
