Show HN: s3-lambda – Lambda functions over S3 objects: each, map, reduce, filter
Its weird how S3 seems to be the unwanted stepchild of AWS.<p>So many obvious innovations just aren't turning up.<p>For example, strangely, AWS introduced tagging for S3 resources, but you can't search/filter by tag, nor is the tag even returned when you get a list of objects, you can only get the tag with an object request. The word "pointless" springs to mind.<p>In fact it's strange that there is NO useful filtering at all apart from the very useful folder/hierarchy/prefix filtering.  But apart from that you can't do wildcard searches or filters or date filters or tag filters.<p>I'm building an application right now that needs to get a list of all the jpg files - the only way to do that is get every single object in the bucket and manually filter out the unwanted ones - feels like its 1988 again.<p>It seems like it would also be valuable for there to be alternate interfaces to S3 such as the ability to send data via ftp or SMTP or sftp or whatever, but there are no such interfaces.<p>Hopefully Google will goad AWS into action on S3 innovation by implementing such features.
