Amazon DynamoDB now supports deleting a global secondary index before it finishes building
Now, you can use the Amazon DynamoDB console or the UpdateTable API/CLI to delete a global secondary index even as it’s being created. Previously, you could not cancel the creation of a global secondary index—indexes could only be deleted once they finished building. This can help you save time if you no longer want a global secondary index or if you want a new global secondary index with different attribute projections. To learn more, see Deleting a Global Secondary Index From a Table in the DynamoDB Developer Guide.
