I couldn't find anything in the specification on this, but is there any constraint on the ordering of encoded pages in a column for a row group.
I think in practice most implementations try to dictionary-encode first and then fallback to another encoding if the dictionary doesn't yield benefits or grows too big. But in theory is an ordering of pages described below possible? 1. Dictionary Encoded Page 2. Plain Encoded Page 3. Dictionary Encoded Page Thanks, Micah
