DynamoDB Streams Disabled

What this rule checks

Detects DynamoDB tables without streams enabled.

How to fix it

1. 1Enable DynamoDB Streams for change data capture
2. 2Consider point-in-time recovery for data protection

import { Stack, App } from 'aws-cdk-lib';
import { Construct } from 'constructs';
import * as dynamodb from 'aws-cdk-lib/aws-dynamodb';

new dynamodb.Table(this, 'Table', {
  partitionKey: { name: 'id', type: dynamodb.AttributeType.STRING },
});

import { Stack, App } from 'aws-cdk-lib';
import { Construct } from 'constructs';
import * as dynamodb from 'aws-cdk-lib/aws-dynamodb';

new dynamodb.Table(this, 'Table', {
  partitionKey: { name: 'id', type: dynamodb.AttributeType.STRING },
  stream: dynamodb.StreamViewType.NEW_AND_OLD_IMAGES,
});

CDK Insights pinpoints the exact file and line in your CDK source for every finding, so you can jump straight to the fix.

Intentional? Suppress this finding

Sometimes a flag is deliberate — a genuinely public endpoint, say. You can dismiss dynamodb-streams-disabled and the reason is kept in the report, not silently hidden.

In .cdk-insights.json:

{
  "ignoreRules": [
    { "id": "dynamodb-streams-disabled", "reason": "Why this is intentional" }
  ]
}

Or inline in your CDK code:

Validations.of(scope).acknowledge({
  id: 'cdk-insights::dynamodb-streams-disabled',
  reason: 'Why this is intentional',
});

Use the rule ID dynamodb-streams-disabled shown above — not the CDK-* ID from SARIF / GitHub code scanning. To dismiss every finding on one construct instead, use ignorePaths. Suppression docs →
