> Oversized dictionary pages, though not violating any format constraints, may be surprising to the user. I believe most size limits indicate they are a best effort, not a hard cutoff. > The data pages of the column chunk are then encoded piecemeal using first the dictionary, then a fallback encoding, which is again legal but weird. Actually this is quite common. Even parquet-java will do this if the dictionary only becomes too large after writing several pages. -- This is an automated message from the Apache Git Service.
