AWS DynamoDB Schema Design | How to choose the right key

AWS DynamoDB Tutorial. DynamoDB is a powerful fully managed NoSQL database. Part of the complexity in using the service is related to choosing a partition key that not only serves your access patterns, but prevents you from having scaling related headaches in the future. In this video, I talk about the factors you should consider when choosing a partition key. I start out by briefly talking about why choosing the right key is important, followed by defining partition and sort keys. Afterwards we go into key partitioning behavior and a feature called adaptive capacity. Finally, I conclude with some general guidance on when you should choose one key structure over another.
