Configuration for Amazon DynamoDB includes adding or modifying database instances and table groups.
Considerations
Consider the following while configuring DynamoDB instances:
-
Backup and restore operations using S3 Export are region-specific as the S3 path provided cannot be cross-region.
-
The combination of Commvault cloud account, DynamoDB table region, and Commvault DynamoDB Instance must be unique. Therefore, ensure to configure one DynamoDB instance per region using a unique cloud account.
-
You cannot create multiple Commvault DynamoDB instances for a given region and cloud account. If there is a need to add multiple tables from the same region, instead of creating multiple instances, consider creating table groups in the existing Commvault DynamoDB Instance. For more information, see Creating a Table Group.
For example, if there is a cloud account 'A' in ap-south-2 region, you can create only one instance in that region. To add more tables from the same region, create a table group in the existing instance.
-
If you want to create a new DynamoDB instance in the same region, you must use a new cloud account. For more information, see Creating a Cloud Database Instance for Amazon DynamoDB Using a New AWS Account.
