Performing auto-retries on DynamoDB errors

As mentioned in the previous recipe, we can perform auto-retries on DynamoDB requests if we get errors. In this recipe, we are going to see how to perform auto-retries.

Getting ready

To get started with this recipe, you should have your workstation ready with the Eclipse IDE.

How to do it…

Auto-retries are required if we get any errors during the first request. We can use the Amazon client configurations to set our retry strategy. By default, the DynamoDB client auto-retries a request if any error is generated three times. If we think that this is not efficient for us, then we can define this on our own, as follows:

1. First of all, we need to create a custom implementation of RetryCondition. It contains a method called shouldRetry, which we need to implement as per our needs. Here is a sample CustomRetryCondition class:

   public class CustomRetryCondition implements RetryCondition {
     public boolean shouldRetry(AmazonWebServiceRequest originalRequest,
     ...
