In general sounds very cool @tustvold > preserve_dictionaries - preserve dictionary encoding for dictionary columns What is the reason for defaulting this one to false? For any string dictionary column this is likely to almost always be what is wanted. > This DictionaryArrayReader will return an error if it encounters a non-dictionary encoded page I can't remember if a single column can have pages encoded using dictionary and non dictionary encoding; I think it is possible but I don't know if any real files have such a thing -- This is an automated message from the Apache Git Service.
