--------------------------------------------------------------------
Updated the requirements doc, seems more or less complete for this go around.
Please let me know if you see something that needs addressing.
Here is the old interface:
{code}
create_indicator_variables (
source_table,
output_table,
categorical_cols,
keep_null, -- Optional
distributed_by -- Optional
)
{code}
Here is the proposed new interface:
{code}
encode_categorical_variables (
source_table,
output_table,
categorical_cols,
categorical_cols_to_exclude, -- Optional
row_id, -- Optional
top, -- Optional
value_to_drop, -- Optional
keep_null, -- Optional
array_output, -- Optional
output_col_dictionary, -- Optional
distributed_by -- Optional
