Answer: The default null threshold is set to .05, meaning that if a column has over 5% null values, it will automatically be dropped. You can override this from the augmentation page in the Global section of the One AI configuration. This field accepts a single float corresponding to the minimum fraction of null values allowed in a column. Any column with more nulls than the allowed threshold will be dropped. For example, if the Null Drop Threshold is set to .3, any column that has more than 30% nulls will be dropped.
