@Josiah ah right, sorry. i'd repeat what i said in %zI07XPN... and %cyl8rmf..., we should do this in a flumeview.
we'll need a new flume index which looks for about messages with tags keys, which provides a lookup for userId -> tag -> messages. so i can see the current messages marked with a specific tag, or all tags marked by a specific user.
@matt what would you recommend as an index order? userId -> tag -> messages, or tag -> userId -> messages, or?
