Moreover, even if you had gone to the trouble of building such an API, S3 still doesn't offer bulk operations, so you'd have to operate on each matching object... one object at a time.
This isn't such an issue because you can update the DynamoDB index using an AWS Lambda function on every putobject or removeobject event.
It's still not something I want to do, mainly because I'd have to touch DynamoDB but secondly because, well, why the heck doesn't AWS do it?
What do you have against DynamoDB?
