Details
-------
This node creates a new DataFrame by casting the specified columns into new types.


Option to replace existing column or create a new column after conversion can be selected in the node.


Examples
-------
Incoming Dataframe has following rows:


::

    INV_NO    |    INV_DATE          |    INV_AMT       
    ----------------------------------------------------
    STRING    |    STRING            |    STRING       
    ----------------------------------------------------
    INV001    |    2010-12-28        |    1000.0        
    INV002    |    2020-10-15        |    1500.0        
    INV003    |    2010-01-01        |    100.0         


if MultiCastColumnType node is configured to perform conversions as below:


::

    COLUMNS    |    NEW DATA TYPE    |    REPLACE EXISTING COLS     
    --------------------------------------------------------------
    INV_DATE   |    DATE             |    false
    INV_DATE   |    LONG             |    false


then new columns would be added in outgoing Dataframe as below after conversion:


::

    INV_NO    |    INV_DATE          |    INV_AMT       |    INV_DATE-new  |    INV_AMT-new       
    ------------------------------------------------------------------------------------------
    STRING    |    STRING            |    STRING        |    DATE          |    LONG       
    ------------------------------------------------------------------------------------------
    INV001    |    2010-12-28        |    1000.0        |    2010-12-28    |    1000        
    INV002    |    2020-10-15        |    1500.0        |    2020-10-15    |    1500        
    INV003    |    2010-01-01        |    100.0         |    2010-01-01    |    100
