Package io.deephaven.server.arrow

Class ArrowFlightUtil.DoExchangeMarshaller

java.lang.Object

io.deephaven.engine.liveness.SingletonLivenessManager

io.deephaven.server.arrow.ArrowFlightUtil.DoExchangeMarshaller

All Implemented Interfaces:

io.deephaven.engine.liveness.LivenessManager, io.deephaven.engine.liveness.ReleasableLivenessManager, io.grpc.stub.StreamObserver<InputStream>, Closeable, AutoCloseable

Enclosing class:

ArrowFlightUtil

public static class ArrowFlightUtil.DoExchangeMarshaller
extends io.deephaven.engine.liveness.SingletonLivenessManager
implements io.grpc.stub.StreamObserver<InputStream>, Closeable

Helper class that maintains a subscription whether it was created by a bi-directional stream request or the no-client-streaming request. If the SubscriptionRequest sets the sequence, then it treats sequence as a watermark and will not send out-of-order requests (due to out-of-band requests). The client should already anticipate subscription changes may be coalesced by the BarrageMessageProducer.
