AWS - Enabling/Disabling DynamoDB Stream programmatically

How to Enable/Disable AWS DynamoDB Stream programmatically?

It would be useful for testing purposes, through automation code, to enable or disable AWS DynamoDB Streams to Lambda. Let's see how to achieve that.

• Make sure you have setup AWS Client credentials (refer: https://balatamilmani.blogspot.com/2020/10/setting-up-aws-client-credentials.html)
• Execute the following code, set variable 'enable' to false to Disable the Stream and true to enable.
• Complete source code can be checked out from https://github.com/balatamilmani/aws-repo.git (Class: DynamoDBDisableStream.java)

           boolean enable = false;//false-to disable, true to enable  
           String dynamoDBTable = "TableName";  
           // Create Async client  
           AmazonDynamoDBAsync ddb = AmazonDynamoDBAsyncClientBuilder.defaultClient();  
           // Create StreamSpecification  
           StreamSpecification streamSpecification = new StreamSpecification();  
           streamSpecification.setStreamEnabled(enable);  
           // StreamViewType is needed only for enabling  
           if (enable) {  
                streamSpecification.setStreamViewType(StreamViewType.NEW_AND_OLD_IMAGES);  
           }  
           // Create update request using the StreamSpecification  
           UpdateTableRequest updateTableRequest = new UpdateTableRequest();  
           updateTableRequest.setTableName(dynamoDBTable);  
           updateTableRequest.setStreamSpecification(streamSpecification);  
           // Execute the update request Asynchronously  
           Future<UpdateTableResult> updateResultFuture = ddb.updateTableAsync(updateTableRequest);  

• Reattach if any Lambda Trigger back to the Stream otherwise any existing Lambda trigger won't work as they got removed during this process, refer to this Blog

Note: The program is not exiting after executing the request, not sure it's due to wrong implementation of the Async API of 'AmazonDynamoDBAsync' code. Please comment if you have a solution to exit from the program gracefully. I ran the program on Java (11.0.8) with AWS DynamoDB SDK (1.11.881) and also using Java 1.8.0_272 as well with no luck
