Interface Summary
Interface	Description
CatalystScan	::Experimental:: An interface for experimenting with a more direct connection to the query planner.
CreatableRelationProvider
DataSourceRegister	Data sources should implement this trait so that they can register an alias to their data source.
InsertableRelation	A BaseRelation that can be used to insert data into it through the insert method.
PrunedFilteredScan	A BaseRelation that can eliminate unneeded columns and filter using selected predicates before producing an RDD containing all matching tuples as Row objects.
PrunedScan	A BaseRelation that can eliminate unneeded columns before producing an RDD containing all of its tuples as Row objects.
RelationProvider	Implemented by objects that produce relations for a specific kind of data source.
SchemaRelationProvider	Implemented by objects that produce relations for a specific kind of data source with a given schema.
StreamSinkProvider	::Experimental:: Implemented by objects that can produce a streaming `Sink` for a specific format or system.
StreamSourceProvider	::Experimental:: Implemented by objects that can produce a streaming `Source` for a specific format or system.
TableScan	A BaseRelation that can produce all of its tuples as an RDD of Row objects.

Class Summary
Class	Description
AlwaysFalse	A filter that always evaluates to `false`.
AlwaysTrue	A filter that always evaluates to `true`.
And	A filter that evaluates to `true` iff both `left` or `right` evaluate to `true`.
BaseRelation	Represents a collection of tuples with a known schema.
EqualNullSafe	Performs equality comparison, similar to `EqualTo`.
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`.
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`.
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 ends with `value`.
StringStartsWith	A filter that evaluates to `true` iff the attribute evaluates to a string that starts with `value`.
