  - ### Method Detail

    - #### writeGraphRDD

          public void writeGraphRDD(Configuration configuration,
                                    <any> graphRDD)

      Description copied from interface: `OutputRDD`
      Write the graphRDD to an output location. The `Configuration` maintains the specified location via `Constants.GREMLIN_HADOOP_OUTPUT_LOCATION`.
      Specified by:
        `writeGraphRDD` in interface `OutputRDD`
      Parameters:
        `configuration` - the configuration of the Spark job
        `graphRDD` - the graphRDD to output

    - #### writeMemoryRDD

          public <K,V> Iterator<KeyValue<K,V>> writeMemoryRDD(Configuration configuration,
                                                              String memoryKey,
                                                              <any> memoryRDD)

      Description copied from interface: `OutputRDD`
      Write the sideEffect memoryRDD to an output location. The `Configuration` maintains the specified location via `Constants.GREMLIN_HADOOP_OUTPUT_LOCATION`. The default implementation returns an empty iterator.
      Specified by:
        `writeMemoryRDD` in interface `OutputRDD`
      Type Parameters:
        `K` - the key class of the RDD
        `V` - the value class of the RDD
      Parameters:
        `configuration` - the configuration of the Spark job
        `memoryKey` - the memory key of the memoryRDD
        `memoryRDD` - the memoryRDD
      Returns:
        the `KeyValue` iterator to store in the final resultant `Memory`.
