Support GSI and LSI through DynamoDB Table

[jungseoklee]

Hi AWS CDK,

First of all, I am happy to see this project :)

As DynamoDB user, it would be great to support GSI and LSI through DynamoDB Table. Currently, a low-level approach is required as follows if GSI or LSI is needed, which makes high-level methods, such as addPartitionKey and addSortKey, less useful.

new dynamodb.cloudformation.TableResource(this, 'cdk', {
    attributeDefinitions: [
        {
            attributeName: 'foo',
            attributeType: 'S'
        },
        {
            attributeName: 'bar',
            attributeType: 'S'
        }
    ],
    tableName: 'cdk',
    keySchema: [
        {
            attributeName: 'foo',
            keyType: 'HASH'
        },
        {
            attributeName: 'bar',
            keyType: 'RANGE'
        }
    ],
    provisionedThroughput: {
        readCapacityUnits: 10,
        writeCapacityUnits: 10
    },
    globalSecondaryIndexes: [
        {
            indexName: 'cdk-gsi',
            keySchema: [
                {
                    attributeName: 'bar',
                    keyType: 'HASH'
                }
            ],
            projection: {
                projectionType: 'ALL'
            },
            provisionedThroughput: {
                readCapacityUnits: 10,
                writeCapacityUnits: 10
            }
        }
    ]
});

Definitely a missing feature in our dynamo db library

I am curious about how you implement this feature: are you considering sort of public methods, such as addGlobalSecondaryIndex, or a totally different approach?

[eladb]

Yes, something like that should work. If it makes sense, we sometimes also like to provide a declarative syntax via props, but only if it's not too cumbersome.

I close this issue because both GSI and LSI are supported now.
