You can create columns for whatever you want to store in a DynamoDB table, instead of or in addition to storing the full payload. Following Step 3.1: Create a New Item from this tutorial , you would update your put_item code to include all your item details...... The problems with DynamoDB Auto Scaling and how it might be improved AWS announced the long awaited auto scaling capability for DynamoDB, but we found it takes too long to scale up and doesn’t scale up aggressively enough as it’s held back by using consumed capacity as scaling metric rather than actual request count.
