class GRAInstanceBuilder extends Serializable

Builder for an IGRAInstance that behaves efficiently in Spark. The IGRAInstance will be serializable from the driver to the executors. All tasks in an executor will share a single IGRAInstance.

For example: 

val downloadManager = new DownloadManagerBuilder("/pb/downloads").addDownloader(new S3Downloader(spark.sparkContext.hadoopConfiguration)).build()
val graInstance = GRAInstanceBuilder()
  .withDownloadManager(downloadManager)
  .addDataset("s3://my.s3.bucket/pb/routing/data/usa")
  .build()

    Include a routing dataset by specifying the path to the dataset's directory.

    Include a routing dataset by specifying the path to the dataset's directory. If using a remote path then include a DownloadManger when using this builder. Otherwise use a local path to the dataset that exists on every worker node.

    datasetPath

    the path to the dataset's directory

    returns

    this builder with the addition of this dataset
