> Requires PARQUET-1324 and probably quite a bit of extra work  
> Properly implementing this will require dictionary normalization across row 
> groups. When reading a new row group, a fast path that compares the current 
> dictionary with the prior dictionary should be used. This also needs to 
> handle the case where a column chunk "fell back" to PLAIN encoding mid-stream
