> An easy way to prevent gaps in the column encoding used to define column qualifiers is to use the position to define the column qualifier. This only works if:
> * You disallow removes of columns
> * You disallow adding columns to the base table
> This is pretty easy to enforce and will enable column encoding to be used effectively when a base table has many views.
