Overview

Specifies a transform that removes columns from the dataset if all values in the column are ‘null’. By default, Glue Studio will recognize null objects, but some values such as empty strings, strings that are “null”, -1 integers or other placeholders such as zeros, are not automatically recognized as nulls.

end

#null_text_list ⇒ Array<Types::NullValueField>

A structure that specifies a list of NullValueField structures that represent a custom null value such as zero or other value being used as a null placeholder unique to the dataset.

The ‘DropNullFields` transform removes custom null values only if both the value of the null placeholder and the datatype match the data.
