Question: Can we pass objects as an item in DynamoDB?

Answered by Rafal Wilinski
Answer
Yes, DynamoDB supports storing complex data types such as objects and nested objects. These can be stored as binary data using the data type "Binary" or as a string using the data type "String" and converting the object to a JSON format before storing it in the table. However, it is important to note that the maximum item size in DynamoDB is 400 KB, which means that the object or nested objects should be within this limit.
