Type Members

1. case class And(left: Filter, right: Filter) extends Filter with Product with Serializable

   A filter that evaluates to true iff both left or right evaluate to true.

2. abstract class BaseRelation extends AnyRef

   ::DeveloperApi:: Represents a collection of tuples with a known schema.

3. trait CatalystScan extends AnyRef

   ::Experimental:: An interface for experimenting with a more direct connection to the query planner.

4. trait CreatableRelationProvider extends AnyRef

5. trait DataSourceRegister extends AnyRef

   ::DeveloperApi:: Data sources should implement this trait so that they can register an alias to their data source.

6. case class EqualNullSafe(attribute: String, value: Any) extends Filter with Product with Serializable

   Performs equality comparison, similar to EqualTo.

7. case class EqualTo(attribute: String, value: Any) extends Filter with Product with Serializable

   A filter that evaluates to true iff the attribute evaluates to a value equal to value.

8. abstract class Filter extends AnyRef

   A filter predicate for data sources.

9. case class GreaterThan(attribute: String, value: Any) extends Filter with Product with Serializable

   A filter that evaluates to true iff the attribute evaluates to a value greater than value.

10. case class GreaterThanOrEqual(attribute: String, value: Any) extends Filter with Product with Serializable

    A filter that evaluates to true iff the attribute evaluates to a value greater than or equal to value.

11. abstract class HadoopFsRelation extends BaseRelation with FileRelation with Logging

    ::Experimental:: A BaseRelation that provides much of the common code required for relations that store their data to an HDFS compatible filesystem.

12. trait HadoopFsRelationProvider extends AnyRef

    ::Experimental:: Implemented by objects that produce relations for a specific kind of data source with a given schema and partitioned columns.

13. case class In(attribute: String, values: Array[Any]) extends Filter with Product with Serializable

    A filter that evaluates to true iff the attribute evaluates to one of the values in the array.

14. trait InsertableRelation extends AnyRef

    ::DeveloperApi:: A BaseRelation that can be used to insert data into it through the insert method.

15. case class IsNotNull(attribute: String) extends Filter with Product with Serializable

    A filter that evaluates to true iff the attribute evaluates to a non-null value.

16. case class IsNull(attribute: String) extends Filter with Product with Serializable

    A filter that evaluates to true iff the attribute evaluates to null.

17. case class LessThan(attribute: String, value: Any) extends Filter with Product with Serializable

    A filter that evaluates to true iff the attribute evaluates to a value less than value.

18. case class LessThanOrEqual(attribute: String, value: Any) extends Filter with Product with Serializable

    A filter that evaluates to true iff the attribute evaluates to a value less than or equal to value.

19. case class Not(child: Filter) extends Filter with Product with Serializable

    A filter that evaluates to true iff child is evaluated to false.

20. case class Or(left: Filter, right: Filter) extends Filter with Product with Serializable

    A filter that evaluates to true iff at least one of left or right evaluates to true.

21. abstract class OutputWriter extends AnyRef

    ::Experimental:: OutputWriter is used together with HadoopFsRelation for persisting rows to the underlying file system.

22. abstract class OutputWriterFactory extends Serializable

    ::Experimental:: A factory that produces OutputWriters.

23. trait PrunedFilteredScan extends AnyRef

    ::DeveloperApi:: A BaseRelation that can eliminate unneeded columns and filter using selected predicates before producing an RDD containing all matching tuples as Row objects.

24. trait PrunedScan extends AnyRef

    ::DeveloperApi:: A BaseRelation that can eliminate unneeded columns before producing an RDD containing all of its tuples as Row objects.

25. trait RelationProvider extends AnyRef

    ::DeveloperApi:: Implemented by objects that produce relations for a specific kind of data source.

26. trait SchemaRelationProvider extends AnyRef

    ::DeveloperApi:: Implemented by objects that produce relations for a specific kind of data source with a given schema.

27. case class StringContains(attribute: String, value: String) extends Filter with Product with Serializable

    A filter that evaluates to true iff the attribute evaluates to a string that contains the string value.

28. case class StringEndsWith(attribute: String, value: String) extends Filter with Product with Serializable

    A filter that evaluates to true iff the attribute evaluates to a string that starts with value.

29. case class StringStartsWith(attribute: String, value: String) extends Filter with Product with Serializable

    A filter that evaluates to true iff the attribute evaluates to a string that starts with value.

30. trait TableScan extends AnyRef

    ::DeveloperApi:: A BaseRelation that can produce all of its tuples as an RDD of Row objects.
