| 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

|
| 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 | Description |
|---|---|
| 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. |
