I have a very simple class, with a string type primary key and List type attributes. I want to write an API for adding and removing an item from the attribute list, and saving the changes back to DDB.
The simplest solution I can think of is:
- Read the list (if it exists)
- If it exists, remove or add the item from the List type attribute
- Put the modified object back
Is there a cleaner/simpler way to do this via DynamoDB java API?
