Description
Dictionary page shall be always written to the first position of the column chunk. Unfortunately, we only have one statement about this "hidden" at the encodings doc:
The dictionary page is written first, before the data pages of the column chunk.
This statement is not emphasized enough and not prepared for the potential extension of the available page types. It also should be placed to a more central place of the specification and also in the thrift file.
