How to create revisions automatically when a new file is added to S3?

We're posting a product to the data marketplace that covers a dataset that has new data added every hour. While onboarding we were told we could set something up to automatically create a revision each hour to add the new csv containing new data, but haven't seen any info on how to do this. Anybody know the best way to go about setting up a system like this to keep our data up-to-date? Thanks
