@tustvold My engine assumes a column is either fully dictionary encoded or not, so for my use case I first have to scan the headers of all pages in the a column chunk to assert they're all dictionary encoded, if any of them are not (other than the dictionary page itself of course), I treat the column as not-dictionary encoded, meaning I'll read with a ColumnReader instead of a PageReader and let the library handle the variously encoded pages. -- This is an automated message from the Apache Git Service.
