filling
A key value pair defining the filling method for a column, where the key is the column name and the value is an object which defines the filling logic. You can specify multiple filling methods for a single column.
The supported filling methods and their corresponding options are:
- frontfill:- none(Supported only for target column)
- middlefill:- zero,- value,- median,- mean,- min,- max
- backfill:- zero,- value,- median,- mean,- min,- max
- futurefill:- zero,- value,- median,- mean,- min,- max
To set a filling method to a specific value, set the fill parameter to the chosen filling method value (for example "backfill" : "value"), and define the filling value in an additional parameter prefixed with "_value". For example, to set backfill to a value of 2, you must include two parameters: "backfill": "value" and "backfill_value":"2".
