How can I retrieve all the values from a particular column in amazon DynamoDB?

Question

For example, if my Question table has columns question_id, options,timestamp, I must retrieve all the values of only 'question_id'.

Is it possible?

Answer 1

First, you need a Scan operation to read all the items regardless of any key value.

Second, you can use a projection expression to specify particular columns of the returned values from server side (to save network bandwidth). See documentation page.
