Interface ScatterGatherBackingStore

All Superinterfaces:
AutoCloseable, Closeable
All Known Implementing Classes:
FileBasedScatterGatherBackingStore

public interface ScatterGatherBackingStore extends 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.
