How to go around filtering data to extract values every hour from DB

<*** class="md">Hi!

Im using DynamoDB to store data coming from IoT sensors (I receive data every 20 minutes). Right now, I have been capturing data for around a month.

So my question is if I want to do a query that filters the database and return the data every 1 or 2 hours instead of every 20 minutes, what would be the best way to do this.

I can think about a couple of ways to go around this in js, but not sure if they are efficient and not sure even how to google it.

any ideas are welcome

Thanks!.
