public final class StreamResultFuture extends com.google.common.util.concurrent.AbstractFuture<StreamState>
StreamState
) of a streaming plan.
In practice, this object also groups all the StreamSession
for the streaming job
involved. One StreamSession will be created for every peer involved and said session will
handle every streaming (outgoing and incoming) to that peer for this job.
The future will return a result once every session is completed (successfully or not). If any session ended up with an error, the future will throw a StreamException.
You can attach StreamEventHandler
to this object to listen on StreamEvent
s to
track progress of the streaming.
