def apply(frame: DynamicFrame,
          missingValuesColumn: String,
          outputColumn: String = "",
          transformationContext: String = "",
          callSite: CallSite = CallSite("Not provided", ""),
          stageThreshold: Long = 0,
          totalThreshold: Long = 0): DynamicFrame

Fills a dynamic frame's missing values in a specified column and returns a new frame with estimates in a new column. For rows without missing values, the specified column's value is duplicated to the new column.

• frame — The DynamicFrame in which to fill missing values. Required.

• missingValuesColumn — The column containing missing values (null values and empty strings). Required.

• outputColumn — The name of the new column that will contain estimated values for all rows whose value was missing. Optional; the default is the value of missingValuesColumn suffixed by "_filled".

• transformationContext — A unique string that is used to identify state information (optional).

• callSite — Used to provide context information for error reporting. (optional).

• stageThreshold — The maximum number of errors that can occur in the transformation before it errors out (optional; the default is zero).

• totalThreshold — The maximum number of errors that can occur overall before processing errors out (optional; the default is zero).

Returns a new dynamic frame with one additional column that contains estimations for rows with missing values and the present value for other rows.
