DynamoDB is a key-value database, and it's valuable if you have simple scan queries and don't need to do point searches.
Amazon DynamoDB offers excellent scalability, handling data sizes from 100 MB to 1 PB, ideal for on-demand use cases with competitive pricing. As a NoSQL database, it efficiently manages unstructured data with automatic scalability and fast performance. However, querying limitations affect BI applications, and data management functionality is less robust than competitors. Pricing can escalate with larger databases, and stability and security concerns persist, potentially impacting cost efficiency and configuration simplicity.
