dynamodb-migration

Example code for migrating data between tables using DynamoDB Streams.

Usage

Follow these instructions if you want to play around with the example code.

Deployment

Make sure you have the SAM CLI tool installed.

sam deploy --stack-name dynamodb-migration-example --capabilities CAPABILITY_IAM

Populate data

Add any number of items to the OriginalBooksTable. Each item should at least contain the following properties:

{
  "isbn": "some-isbn",
  "author": "some-author",
  "title": "some-title"
}

Run migration script

If you want to try out the migration script (see step 3 in the blog post).

First, delete every item in the TargetBooksTable.

To run the migration script:

cd migrate-data
npm install
node app.js

This will add a migrate property to every item in OriginalBooksTable, in order to trigger the migration stream even for items that were added before the stream was in place.
