Note the 10MB minimum "charge" per Query. For small datasets under 10MB, you'd only get up to 200 Queries for the minimum billable $0.01. That would be a fairly small number of queries, so probably not that useful. Plus you'd have all kinds of issues regarding consistency if your data was dynamic (s3 is a blob store, not a database, normal s3 consistency guarantees still apply).

I'm confused though. The monthly fees for dynamodb only apply after you exceed the free tier, and for someone who is unable to commit to a monthly fee because they envision low usage, shouldn't the free tier be sufficient? (Honest question, I'm looking at using dynamodb, but comments like this make me think I'm missing something)

Only thing you're missing is that I didn't realize DynamoDB's free tier was a non-expiring free tier.
