How to implement pagination when using amazon Dynamo DB in rails

Question

I want to use amazon Dynamo DB with rails.But I have not found a way to implement pagination.

I will use AWS::Record::HashModel as ORM.

This ORM

Answer 1

You can provide 'page-size' in you query to set the result set size. The response of DynamoDB contains 'LastEvaluatedKey' which will indicate the last key as per the page size. If response does't contain 'LastEvaluatedKey' it means there are no results left to fetch. Use the 'LastEvaluatedKey' as 'ExclusiveStartKey' while fetching next time.

I hope this helps.
