Loading and writing data using GraphSON

The Tinkerpop GraphSON Reader can be used to load and write data.

  1. Start the Gremlin console.

  2. Start a graph instance and create the schema.

  3. Use the DSE Graph Loader to load the GraphSON file.

  4. Writing data out of the graph into a GraphSON file while capturing the original data types of the inserted data can be accomplished with a short script:

    gremlin> f = new FileOutputStream("/tmp/recipe_lossless.json");
    mapper = graph.io(graphson()).mapper().embedTypes(true).create();

    A sample of the output shows the class information and data types:
