Announcing incremental export to S3 for Amazon DynamoDB

Today, Amazon DynamoDB announces the general availability of incremental export to S3, that allows you to export only the data that has changed within a specified time interval. With incremental exports, you can now export data that was inserted, updated or deleted, in small increments. You can export changed data ranging from a few megabytes to terabytes with a few clicks in the AWS Management Console, an API call, or the AWS Command Line Interface. Choose a DynamoDB table that has point-in-time-recovery enabled, specify an export time period for which you want incremental data, choose your target Amazon S3 bucket, and export.
