Exporting data from DynamoDB
There might be many places where your application data that is stored in DynamoDB needs
to be exported to flat files. This exercise could be a part of data archiving, data purging, or
some data movement. Even when you need to perform data analytics on DynamoDB data
using EMR you can either first export it to S3 or to
Hadoop Distributed File System
(
HDFS
). Now let's learn how to export data to S3/HDFS in a stepwise manner.
The pre-requisites to perform this exercise are as follows:
• An EMR Hadoop cluster with Hive installed
• A simple AWS S3 bucket
• A DynamoDB table with some data to be exported
• Knowledge of HiveQL/Hadoop
