AppendableRowsAndColumns (druid-processing 28.0.1 API)

All Superinterfaces:

RowsAndColumns

All Known Implementing Classes:

AppendableMapOfColumns, ArrayListRowsAndColumns
```
public interface AppendableRowsAndColumns
extends RowsAndColumns
```
A RowsAndColumns that supports appending columns. This interface is particularly useful because even if there is some composition of code that works with RowsAndColumns, we would like to add the columns to a singular base object instead of build up a complex object graph.
