How to check what version of Aurora Serverless I have?

To determine if you have Aurora Serverless v1 or v2:

Check the DB engine version in the AWS Management Console. Use the AWS CLI or AWS SDK to query the DB cluster properties. The version format (mysql_aurora.1.x.x for v1 and mysql_aurora.2.x.x for v2) will indicate which version you are using.

To check which version of Aurora Serverless you have, you can follow these steps:

1. Sign in to the AWS Management Console and open the Amazon RDS console.
2. In the navigation pane, choose "Databases" to view your DB clusters.
3. Look at the "Role" column for your Aurora clusters. Aurora Serverless v1 DB clusters will be identified as "Serverless" under the "Role" column.

For Aurora Serverless v2, it's important to note that it's not explicitly labeled as "Serverless v2" in the console. Instead, Aurora Serverless v2 is considered an instance type rather than a separate category. To identify if you're using Aurora Serverless v2:

1. Select your Aurora cluster.
2. Check the "Configuration" tab.
3. Look at the "Instance type" for your writer and reader instances. If it shows "Serverless v2" or mentions ACUs (Aurora Capacity Units), you're using Aurora Serverless v2.

Additionally, you can infer which version you're using based on the database engine version:

• For Aurora MySQL:

  • Serverless v1 runs on older versions (e.g., 5.6, 5.7)
  • Serverless v2 runs on Aurora MySQL 3 (MySQL 8.0 compatible)

• For Aurora PostgreSQL:

  • Serverless v1 runs on version 13
  • Serverless v2 runs on version 13 and higher

If you're still unsure, you can check the scaling properties and features of your cluster, as Serverless v2 offers more granular scaling and compatibility with features like reader instances, which are not available in Serverless v1.
