Question: Can DynamoDB store blob data?

Answered by Rafal Wilinski
Answer
BLOB data is known as Binary Large Object Storage. In DynamoDB, it can store binary items up to 400KB. Hence, DynamoDB can store blobs that are 400KB in size. However, this is not recommended as it negatively impacts performance and scalability. Therefore, AWS recommends storing blobs in S3 and persisting a path to the item on DynamoDB to access blobs.
