What is an appropriate business scenario where a key-value document-based database like DynamoDB would be used?
A business scenario where DynamoDB would be useful is when a high-flow system is in place. It's designed for scalability and performance in systems like these. The system can handle large amounts of data and transactions quickly and reliably. What’s the best practice for isolating frequently used items?
The best thing you can do if your application drives more traffic to one item is to isolate the item.
It is best to use a specific partition key for isolating frequently used items. A partition key can ensure that frequently used items are stored separately from other items, making it easier for you to access them.
When should you use a DynamoDB Rule compared to other rules, such as Lambda Action and SNS?
Using DynamoDB Rules over Lambda Actions and SNS is better if you need flexibility and have
a large data set. DynamoDB Rules are easier to manage and scale than Lambda Actions and SNS.
