Type Parameters:

T - the row type

R - the result type

```
public interface PartitioningWriter<T,R>
extends java.io.Closeable
```
A writer capable of writing files of a single type (i.e. data/delete) to multiple specs and partitions.
As opposed to FileWriter, this interface should be implemented by writers that are not limited to writing to a single spec/partition. Implementations may internally use FileWriters for writing to a single spec/partition.
Note that this writer can be used both for partitioned and unpartitioned tables.
