Example code for migrating data between tables using DynamoDB Streams.
Follow these instructions if you want to play around with the example code.
Make sure you have the SAM CLI tool installed.
sam deploy --stack-name dynamodb-migration-example --capabilities CAPABILITY_IAM
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"
}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.
