case class StreamingRelation(dataSource: DataSource, sourceName: String, output: Seq[Attribute]) extends LogicalPlan with LeafNode with MultiInstanceRelation with ExposesMetadataColumns with Product with Serializable

Used to link a streaming DataSource into a org.apache.spark.sql.catalyst.plans.logical.LogicalPlan. This is only used for creating a streaming org.apache.spark.sql.DataFrame from org.apache.spark.sql.DataFrameReader. It should be used to create Source and converted to StreamingExecutionRelation when passing to StreamExecution to run a query.
