Question: Can DynamoDB have duplicates?
Answered by Rafal Wilinski
Answer
DynamoDB is a NoSQL database provided by Amazon Web Services (AWS) that uses a unique primary key to identify each item in a table. By default, it does not allow duplicates. However, if you are using a secondary index, there is a possibility of duplicates if the indexed attributes are not unique.
