DynamoDB is an incredibly powerful NoSQL database. It’s schema-less, which gives you lots of flexibility, but it also means that you are responsible for managing the integrity of your data. This includes ensuring the structure of your data, as well as the ability to preserve metadata throughout your data’s lifecycle.
Unfortunately, DynamoDB doesn’t currently store any metadata associated with items. If you want to know when a particular item was written to the table, for example, you have to store that information yourself. While it’s not particularly difficult to add these attributes to an item, maintaining their integrity can come with some challenges.
In this article, we’ll discuss several strategies that can be used to ensure data integrity in your DynamoDB tables.
