Troubleshooting in Amazon DynamoDB

The following are common problems and their solutions:

• If error logging is not enabled then enable it and check error log messages.
• Verify whether the DynamoDB table exists or not.
• Verify the IAM role specified for DynamoDB and its access permissions.
• AWS SDKs take care of propagating errors to your application for appropriate actions. Like Java programs, you should write a try-catch block to handle the error or exception.
• If you are not using an AWS SDK then you need to parse the content of low-level responses from DynamoDB.
• A few exceptions are as follows:
  • AmazonServiceException: Client request sent to DynamoDB but DynamoDB was unable to process it and returned an error response
  • AmazonClientException: Client is unable to get a response or parse the response from service
  • ResourceNotFoundException: Requested table doesn't exist or is in CREATING state
