Logging operations in Amazon DynamoDB

We have already established that DynamoDB is a serverless NoSQL database engine. This service is proprietary to AWS, although you can get it as a Docker image here:

Important note

The architecture of NoSQL databases is quite different from the relational database management system. For DynamoDB, AWS has abstracted a lot of the operational things that we should be worried about, so our focus on the metrics will be more on the database layer than the infrastructure running the database. In DynamoDB, one of the most critical metrics to watch out for is the database's read and write capacities. These determine the behavior and the availability of your DynamoDB tables. They are measured...
