   I think we should be really careful with allowing filtering on arbitrary data columns. In a lot of cases, this may end up useless or even degrade the performance. We currently only allow filtering on data columns used as source fields for partition transforms.
   
   I would consider allowing filtering by sort columns defined in the table. However, I would probably (not sure) hide it under a flag so that users would have to opt in.
   
   Thoughts, @rdblue @RussellSpitzer?
