(dynamodb): Dynamo TableV2 does not work with Tags.of

[ckuehne]

Describe the bug

The aws_dynamodb.TableV2 construct does not support adding tags via Tags.of.

I.e., the following code does not create the myKey tag.

import * as cdk from 'aws-cdk-lib';
import {aws_dynamodb, Tags} from "aws-cdk-lib";

const app = new cdk.App();
const stack = new cdk.Stack(app, 'Stack');

const globalTable = new aws_dynamodb.TableV2(stack, 'GlobalTable', {
    partitionKey: {name: 'pk', type: aws_dynamodb.AttributeType.STRING},
});

Tags.of(globalTable).add('myKey', 'myValue');

Expected Behavior

Creates tag.

Current Behavior

Does not create tag.

Reproduction Steps

import * as cdk from 'aws-cdk-lib';
import {aws_dynamodb, Tags} from "aws-cdk-lib";

const app = new cdk.App();
const stack = new cdk.Stack(app, 'Stack');

const globalTable = new aws_dynamodb.TableV2(stack, 'GlobalTable', {
    partitionKey: {name: 'pk', type: aws_dynamodb.AttributeType.STRING},
});

Tags.of(globalTable).add('myKey', 'myValue');

Suggestion: Try using aspects to add tags to the current stack where Aspect is called.

Yes, this would work. But still the buggy behaviour is unexpected and should be fixed.

[Tirush Venamadala]

Thats true. I agree with you.

I had this use case before and solved it by getting the all event notification first inside a list and then recreating then along with new one again. (Temporary solution) XD

Hey @ckuehne , thanks for reporting this. I reproduced this issue and agree that this is a buggy behavior. Hence marking it as P3.

However if you try assigning the tags like this, this adds the tags to the table. Usage of ASPECTS (sample code) would also be another workaround

    const globalTable = new aws_dynamodb.TableV2(this, 'GlobalTable', {
      partitionKey: {name: 'pk', type: aws_dynamodb.AttributeType.STRING},
      tags: [{key: "myKeyTag", value: "myValueTag"}]
    });
