Summary
In this chapter, we have learned about Amazon DynamoDB. We have learned how to create a DynamoDB table and how to use different index types to query the data. We also learned how to scan the table for cases where we cannot use an index. We learned how DynamoDB is priced and some techniques to minimize costs.
In the AWS Certified Database – Specialty exam, your knowledge of DynamoDB will be tested heavily with questions around common error codes, service limits, index types and their key features, and backup and restore methods.
In the next chapter, we will be learning about Redshift and DocumentDB, which are both AWS databases with specific use cases. We will continue to use the knowledge learned in this chapter to interact with Redshift and DocumentDB, as they have many similarities with DynamoDB.
