RelationProvider

trait RelationProvider extends AnyRef

::DeveloperApi:: Implemented by objects that produce relations for a specific kind of data source. When Spark SQL is given a DDL operation with a USING clause specified, this interface is used to pass in the parameters specified by a user.

Users may specify the fully qualified class name of a given data source. When that class is not found Spark SQL will append the class name DefaultSource to the path, allowing for less verbose invocation. For example, 'org.apache.spark.sql.json' would resolve to the data source 'org.apache.spark.sql.json.DefaultSource'

A new instance of this class with be instantiated each time a DDL call is made.
