Prerequisites
You must have a valid Liquibase Pro license to use this policy check.
You must download the Liquibase AWS extension jar and save it to your /lib folder.
Uses
Use this check to enforce naming conventions, security standards, or deployment rules by validating specific fields in DynamoDB change types. You can define multiple checks with different attributes and patterns to match your standards across various Change types.
When does this check trigger?
This check is fully driven by how you configure it. Once configured, the check will trigger only when all of the following are true:
A changeset contains the specific Change type you specified, such as
createDynamoTable.That Change type includes the attribute that you're checking, such as
billingMode.
If the Change type isn’t used, or the attribute isn’t present, the check doesn’t run. This ensures you're only enforcing rules when that part of the changelog is relevant.
Procedure
Procedure
This check is disabled by default. To enable it, run the enable command:
liquibase checks enable --check-name=DynamoChangetypeAttributesLiquibase will prompt you to name your custom version of the check.
By default, it will be named DynamoChangetypeAttributes1. You can accept the default by pressing Enter or enter a custom name.
Set the severity level. This determines the exit code when the check is triggered.
INFO (0)
MINOR (1)
MAJOR (2)
CRITICAL (3)
BLOCKER (4)
Set the DynamoDB changetype this check will inspect.
You’ll be prompted with:

Once you've selected the changetype, you'll be walked through its specific attributes.
