You are working for a start-up company using Amazon DynamoDB for mobile applications. During performing POC for a new application using AWS SDK, most of the cases are successfully executed, but for certain cases, Amazon DynamoDB is returning the ThrottlingException error message. Development Team is asking for your help to suggest a solution to reduce the number of these errors. Which of the following method is the most suitable?

Answer options:

A.Retry the DynamoDB operations when the error happens.
B.Modify the application by adding a five seconds timer before sending a DynamoDB request.
C.Scale up the DynamoDB table by allocating more read/write capacities.
D.Use AWS DynamoDB SDK in the application that optimizes the DynamoDB operations.

Correct Answer – C
Option A is incorrect because this method cannot reduce the number of errors. This method can be used to mitigate the impacts when the error happens.
Option B is incorrect because five seconds timer may not be suitable for the application and it needs the code change as well. This is not the most suitable solution.
Option C is CORRECT because with more read/write capacities in the table, the DynamoDB table can process more read/write requests, which can reduce the number of ThrottlingException errors.
Option D is incorrect because the application may already use the AWS DynamoDB SDK so this option will not help.
