This is a developer preview (public beta) module. Releases might lack important features and might have future breaking changes.

This API is still under active development and subject to non-backward compatible changes or removal in any future version. Use of the API is not recommended in production environments. Experimental APIs are not subject to the Semantic Versioning model.

Global Tables builds upon DynamoDB’s global footprint to provide you with a fully managed, multi-region, and multi-master database that provides fast, local, read and write performance for massively scaled, global applications. Global Tables replicates your Amazon DynamoDB tables automatically across your choice of AWS regions.

Here is a minimal deployable Global DynamoDB tables definition:

import { AttributeType } from '@aws-cdk/aws-dynamodb';
import { GlobalTable } from '@aws-cdk/aws-dynamodb-global';
import { App } from '@aws-cdk/core';

const app = new App();
new GlobalTable(app, 'globdynamodb', {
  partitionKey: { name: 'hashKey', type: AttributeType.String },
  tableName: 'GlobalTable',
  regions: [ "us-east-1", "us-east-2", "us-west-2" ]
});
app.synth();

Implementation Notes

AWS Global DynamoDB Tables is an odd case currently. The way this package works -

• Creates a DynamoDB table in a separate stack in each DynamoDBGlobalStackProps.region specified
• Deploys a CFN Custom Resource to your stack's specified region that calls a lambda that runs the aws cli which calls createGlobalTable()

Notes

GlobalTable() will set dynamoProps.stream to be NEW_AND_OLD_IMAGES since this is a required attribute for AWS Global DynamoDB tables to work. The package will throw an error if any other stream specification is set in DynamoDBGlobalStackProps.
