Package org.apache.spark.sql.sources

Interface Summary

CatalystScan	::Experimental:: An interface for experimenting with a more direct connection to the query planner.
CreatableRelationProvider
HadoopFsRelationProvider	::Experimental:: Implemented by objects that produce relations for a specific kind of data source with a given schema and partitioned columns.
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.

Class Summary

And	A filter that evaluates to true iff both left or right evaluate to true.
BaseRelation	::DeveloperApi:: Represents a collection of tuples with a known schema.
EqualTo	A filter that evaluates to true iff the attribute evaluates to a value equal to value.
Filter	A filter predicate for data sources.
GreaterThan	A filter that evaluates to true iff the attribute evaluates to a value greater than value.
GreaterThanOrEqual	A filter that evaluates to true iff the attribute evaluates to a value greater than or equal to value.
HadoopFsRelation	::Experimental:: A BaseRelation that provides much of the common code required for formats that store their data to an HDFS compatible filesystem.
In	A filter that evaluates to true iff the attribute evaluates to one of the values in the array.
IsNotNull	A filter that evaluates to true iff the attribute evaluates to a non-null value.
IsNull	A filter that evaluates to true iff the attribute evaluates to null.
LessThan	A filter that evaluates to true iff the attribute evaluates to a value less than value.
LessThanOrEqual	A filter that evaluates to true iff the attribute evaluates to a value less than or equal to value.
Not	A filter that evaluates to true iff child is evaluated to false.
Or	A filter that evaluates to true iff at least one of left or right evaluates to true.
OutputWriter	::Experimental:: OutputWriter is used together with HadoopFsRelation for persisting rows to the underlying file system.
OutputWriterFactory	::Experimental:: A factory that produces OutputWriters.
StringContains	A filter that evaluates to true iff the attribute evaluates to a string that contains the string value.
StringEndsWith	A filter that evaluates to true iff the attribute evaluates to a string that starts with value.
StringStartsWith	A filter that evaluates to true iff the attribute evaluates to a string that starts with value.
