Interface Summary

Interface	Description
CatalystScan	::Experimental:: An interface for experimenting with a more direct connection to the query planner.
CreatableRelationProvider
InsertableRelation	::DeveloperApi:: A BaseRelation that can be used to insert data into it through the insert method.
PrunedFilteredScan	::DeveloperApi:: A BaseRelation that can eliminate unneeded columns and filter using selected predicates before producing an RDD containing all matching tuples as Row objects.
PrunedScan	::DeveloperApi:: A BaseRelation that can eliminate unneeded columns before producing an RDD containing all of its tuples as Row objects.
RelationProvider	::DeveloperApi:: Implemented by objects that produce relations for a specific kind of data source.
SchemaRelationProvider	::DeveloperApi:: Implemented by objects that produce relations for a specific kind of data source with a given schema.
TableScan	::DeveloperApi:: A BaseRelation that can produce all of its tuples as an RDD of Row objects.
