Dynamo-to-ElasticSearch

A NPM module that will dump all DynamoDB data to AWS ElasticSearch indices.

What this does

It takes entire table from DynamoDB and injects it to AWS Elasticsearch service. It may serve as a blueprint in AWS Lambda, however it is not based on streams, but on DynamoDB scan operation.

This module is an extended version of dynamodb-to-elasticsearch. The difference is that here you can set your own primaryKey as well as index type. It is a separate repository as it breaks backward compatibility.

Installation

$ npm install dynamo-to-elasticsearch
