Package com.mapr.kafka.eventstreams.impl.producer

Class MarlinProducerResultImpl

  • All Implemented Interfaces:
    com.mapr.fs.jni.MarlinProducerResult
    Direct Known Subclasses:
    MarlinProducerResultImplV10
    public class MarlinProducerResultImpl
extends java.lang.Object
implements com.mapr.fs.jni.MarlinProducerResult
    This structure maintains all the data structures related to a producer request. Once marlin server comes back with a completion callback for a request then this request is marked done and populated with all the metadata coming from the server. The future returned to the caller waits on this done call to actually return the request metadata.
