    Parameters:
    
    tableConfig - the config for the table
    
    schema - the table schema
- Method Detail
  - getPassThroughPipeline
```
public static TransformPipeline getPassThroughPipeline()
```
    Returns a pass through pipeline that does not transform the record.
  - processRow
```
public void processRow(GenericRow decodedRow,
                       TransformPipeline.Result reusedResult)
                throws Exception

    Process and validate the decoded row against schema.
    
    Parameters:
    
    decodedRow - the row data to pass in
    
    reusedResult - the reused result so we can reduce objects created for each row
    
    Throws:
    
    Exception - when data has issues like schema validation. Fetch the partialResult from Exception
