  15. def saveAsNQuadsFile(graph: String, path: String, writeMode: WriteMode = FileSystem.WriteMode.NO_OVERWRITE): DataSink[String]

    Writes the triples as N-Quads file(s) to the specified location using the given graph.

    Writes the triples as N-Quads file(s) to the specified location using the given graph.

    - A directory is created and multiple files are written underneath. (Default behavior)
    This sink creates a directory called "path1", and files "1", "2" ... are writen underneath depending on parallelism


    .
└── path1/
    ├── 1
    ├── 2
    └── ...

    Code Example

    dataset.saveAsNQuadsFile("file:///path1")

    - A single file called "path1" is created when parallelism is set to 1

    .
└── path1

    Code Example

    // Parallelism is set to only this particular operation
dataset.saveAsNQuadsFile("file:///path1").setParallelism(1)

// This will have the same effect but note all operators' parallelism are set to one
env.setParallelism(1);
...
dataset.saveAsNQuadsFile("file:///path1")

    - A directory is always created when fs.output.always-create-directory is set to true in flink-conf.yaml file, even when parallelism is set to 1.

    .
└── path1/
    └── 1

    Code Example

    // fs.output.always-create-directory = true
dataset.saveAsNQuadsFile("file:///path1").setParallelism(1)
    graph

    The graph used for the N-Quads

    path

    The path pointing to the location the text file or files under the directory is written to.

    writeMode

    Control the behavior for existing files. Options are NO_OVERWRITE and OVERWRITE.

    returns

    The DataSink that writes the DataSet.
