case class EdgeListDataSource(path: String, options: Map[String, String] = Map.empty)(implicit session: CAPSSession) extends PropertyGraphDataSource with Product with Serializable

A read-only data source that is able to read graphs from edge list files. Input files are expected to contain one edge per row, e.g.

0 1 1 2

describes a graph with two edges (one from vertex 0 to 1 and one from vertex 1 to 2). The reader expects the file to not contain any comments.

The data source can be parameterized with options used by the underlying Spark Csv reader.
