I have a long list of dictionaries I am trying to insert into DynamoDB. Each is an item in the table. Each item has a hash key and label key/value pairs with label# being the key and a string as the value pair. Currently, the label# keys within each dictionary are unordered, and when I go to insert each item it is only adding 19 of the fields. So, I was wondering if there a limit on the number of attributes in the DynamoDB Table?
