Description

The save options on DataFrames are not easily discerned:
ResolvedDataSource.apply is where the pattern match occurs:

ddl.scala

case dataSource: SchemaRelationProvider =>
dataSource.createRelation(sqlContext, new CaseInsensitiveMap(options), schema)

Implementing classes are currently: TableScanSuite, JSONRelation, and newParquet
