1. case class Aggregate(groupingExpressions: Seq[Expression], aggregateExpressions: Seq[NamedExpression], child: LogicalPlan) extends UnaryNode with Product with Serializable

   

2. abstract class BinaryNode extends LogicalPlan with trees.BinaryNode[LogicalPlan]

   

   A logical plan node with a left and right child.

3. case class CacheTableCommand(tableName: String, plan: Option[LogicalPlan], isLazy: Boolean) extends Command with Product with Serializable

   

   Returned for the "CACHE TABLE tableName [AS SELECT ...]" command.

4. abstract class Command extends LeafNode

   

   A logical node that represents a non-query command to be executed by the system.

   A logical node that represents a non-query command to be executed by the system. For example, commands can be used by parsers to represent DDL operations.

5. case class CreateTableAsSelect[T](databaseName: Option[String], tableName: String, child: LogicalPlan, allowExisting: Boolean, desc: Option[T] = None) extends UnaryNode with Product with Serializable

   

6. case class DFSCommand(kv: Option[(String, Option[String])]) extends Command with Product with Serializable

   

   Commands of the form "SET [key [= value] ]".

7. case class DescribeCommand(table: LogicalPlan, isExtended: Boolean) extends Command with Product with Serializable

   

   Returned for the "DESCRIBE [EXTENDED] [dbName.]tableName" command.

   Returned for the "DESCRIBE [EXTENDED] [dbName.]tableName" command.

   table

   The table to be described.

   isExtended

   True if "DESCRIBE EXTENDED" is used. Otherwise, false. It is effective only when the table is a Hive table.

8. case class Distinct(child: LogicalPlan) extends UnaryNode with Product with Serializable

   

9. case class Except(left: LogicalPlan, right: LogicalPlan) extends BinaryNode with Product with Serializable

   

10. case class ExplainCommand(plan: LogicalPlan, extended: Boolean = false) extends Command with Product with Serializable

    

    Returned by a parser when the users only wants to see what query plan would be executed, without actually performing the execution.

11. case class Filter(condition: Expression, child: LogicalPlan) extends UnaryNode with Product with Serializable

    

12. case class Generate(generator: Generator, join: Boolean, outer: Boolean, alias: Option[String], child: LogicalPlan) extends UnaryNode with Product with Serializable

    

    Applies a Generator to a stream of input rows, combining the output of each into a new stream of rows.

    Applies a Generator to a stream of input rows, combining the output of each into a new stream of rows. This operation is similar to a flatMap in functional programming with one important additional feature, which allows the input rows to be joined with their output.

    join

    when true, each output row is implicitly joined with the input tuple that produced it.

    outer

    when true, each input row will be output at least once, even if the output of the given generator is empty. outer has no effect when join is false.

    alias

    when set, this string is applied to the schema of the output of the transformation as a qualifier.

13. case class InsertIntoTable(table: LogicalPlan, partition: Map[String, Option[String]], child: LogicalPlan, overwrite: Boolean) extends LogicalPlan with Product with Serializable

    

14. case class Intersect(left: LogicalPlan, right: LogicalPlan) extends BinaryNode with Product with Serializable

    

15. case class Join(left: LogicalPlan, right: LogicalPlan, joinType: JoinType, condition: Option[Expression]) extends BinaryNode with Product with Serializable

    

16. abstract class LeafNode extends LogicalPlan with trees.LeafNode[LogicalPlan]

    

    A logical plan node with no children.

17. case class Limit(limitExpr: Expression, child: LogicalPlan) extends UnaryNode with Product with Serializable

    

18. case class LocalRelation(output: Seq[Attribute], data: Seq[Product] = Nil) extends LeafNode with MultiInstanceRelation with Product with Serializable

    

19. abstract class LogicalPlan extends QueryPlan[LogicalPlan] with Logging

    

20. case class NativeCommand(cmd: String) extends Command with Product with Serializable

    

    Returned for commands supported by a given parser, but not catalyst.

    Returned for commands supported by a given parser, but not catalyst. In general these are DDL commands that are passed directly to another system.

21. case class Project(projectList: Seq[NamedExpression], child: LogicalPlan) extends UnaryNode with Product with Serializable

    

22. abstract class RedistributeData extends UnaryNode

    

    Performs a physical redistribution of the data.

    Performs a physical redistribution of the data. Used when the consumer of the query result have expectations about the distribution and ordering of partitioned input data.
