Using Amazon Elastic MapReduce With DynamoDB: NoSQL Tutorials
Adam Gray[1]:
In this article, I’ll demonstrate how EMR can be used to efficiently export DynamoDB tables to S3, import S3 data into DynamoDB, and perform sophisticated queries across tables stored in both DynamoDB and other storage services such as S3.
