ScatterGatherBackingStore

All Implemented Interfaces:

java.io.Closeable , java.lang.AutoCloseable
```
public interface ScatterGatherBackingStore
 implements Closeable
                    
```
Store intermediate payload in a scatter-gather scenario. Multiple threads write their payload to a backing store, which can subsequently be reversed to an InputStream to be used as input in the gather phase.
It is the responsibility of the allocator of an instance of this class to close this. Closing it should clear off any allocated structures and preferably delete files.

Method Summary

`abstract InputStream`	`getInputStream()`	An input stream that contains the scattered payload
`abstract void`	`writeOut(Array<byte> data, int offset, int length)`	Writes a piece of payload.
