How to delete a Global DynamoDB table

Question: I want to delete a Global DynamoDB table  using AWS CLI commands if it's a Global Tables version 2019.11.21  version.

Answer: 

Step 1 : You can first identify if it's a Global Table and the version by executing this command.

aws dynamodb describe-table --table-name replace_with_table_name  --query Table.GlobalTableVersion 

Step 2 : If you want to identify the Replica  details of the Global Table 

aws dynamodb describe-table --table-name replace_with_table_name  --query Table.Replicas 

Step 3: The next step is to issue the dynamodb update-table command to delete the Replica .

 aws dynamodb update-table --table-name replace_with_table_name --replica-updates Delete={RegionName=my_regio}

You can confirm if the the Replica is deleted by using the Replica query from above in Step 2 .

Step 4 : Delete the main DynamoDB table. After you've completed Step 3 the DynamoDB table is no longer a Global Table. You can confirm via executing the command in Step 1 to check the GlobalTableVersion 

You can now proceed with deleting the DynamoDB table : 

aws dynamodb delete-table --table-name replace_with_table_name
