Interface TableStreamManager

All Known Implementing Classes:

CassandraStreamManager

public interface TableStreamManager

The main streaming hook for a storage implementation. From here, the streaming system can get instances of StreamReceiver, IncomingStream, and OutgoingStream, which expose the interfaces into the the underlying storage implementation needed to make streaming work.

Method Summary

Modifier and Type	Method and Description
java.util.Collection<OutgoingStream>	createOutgoingStreams(StreamSession session, RangesAtEndpoint replicas, java.util.UUID pendingRepair, PreviewKind previewKind) Returns a collection of OutgoingStreams that contains the data selected by the given replicas, pendingRepair, and preview.
StreamReceiver	createStreamReceiver(StreamSession session, int totalStreams) Creates a StreamReceiver for the given session, expecting the given number of streams
IncomingStream	prepareIncomingStream(StreamSession session, StreamMessageHeader header) Creates an IncomingStream for the given header

Method Detail

createStreamReceiver

StreamReceiver createStreamReceiver(StreamSession session,
                                    int totalStreams)

Creates a StreamReceiver for the given session, expecting the given number of streams

prepareIncomingStream

IncomingStream prepareIncomingStream(StreamSession session,
                                     StreamMessageHeader header)

Creates an IncomingStream for the given header

createOutgoingStreams

java.util.Collection<OutgoingStream> createOutgoingStreams(StreamSession session,
                                                           RangesAtEndpoint replicas,
                                                           java.util.UUID pendingRepair,
                                                           PreviewKind previewKind)

Returns a collection of OutgoingStreams that contains the data selected by the given replicas, pendingRepair, and preview. There aren't any requirements on how data is divided between the outgoing streams
