Keep/Remove Columns

This component offers a quick way to remove (or keep) a select number of fields without changing their specifications or schema. Each column should be provided on a new line. You cannot remove any columns that is used in the calculation of other columns. For example, if the unit_price field is used as an expression to calculate another field, such as the total_cost, attempting to remove unit_price will result in an error.

If you need more control over certain data types, such as specifying the length of string fields, or decimal values, use the Apply Schema component instead as it offers more powerful control over schema manipulation.
