AWS Data Pipeline Restore

Takes data in the format currently output by AWS Data Pipeline DynamoDB export and writes this to local DynamoDB database using batch write (25 items at a time).

Usage

AWS_REGION=eu-west-1 FILE=./export-file.json TABLE=MyTableName node index.js

Why?

For some reason the format exported by AWS Data Pipeline job differs to what's required by SDK params to batchWriteItem. In particular attribute keys exported have initial lowercase whereas SDK requires all caps e.g. bOOL -> BOOL.
