Type Members

1. class CaseInsensitiveMap extends Map[String, String] with Serializable

   

   Builds a map in which keys are case insensitive

2. case class CreateTableUsing(tableIdent: TableIdentifier, userSpecifiedSchema: Option[StructType], provider: String, temporary: Boolean, options: Map[String, String], allowExisting: Boolean, managedIfNoPath: Boolean) extends LogicalPlan with Command with Product with Serializable

   

   Used to represent the operation of create table using a data source.

   Used to represent the operation of create table using a data source.

   allowExisting

   If it is true, we will do nothing when the table already exists. If it is false, an exception will be thrown

3. case class CreateTableUsingAsSelect(tableIdent: TableIdentifier, provider: String, temporary: Boolean, partitionColumns: Array[String], mode: SaveMode, options: Map[String, String], child: LogicalPlan) extends catalyst.plans.logical.UnaryNode with Product with Serializable

   

   A node used to support CTAS statements and saveAsTable for the data source API.

   A node used to support CTAS statements and saveAsTable for the data source API. This node is a UnaryNode instead of a Command because we want the analyzer can analyze the logical plan that will be used to populate the table. So, PreWriteCheck can detect cases that are not allowed.

4. case class CreateTempTableUsing(tableIdent: TableIdentifier, userSpecifiedSchema: Option[StructType], provider: String, options: Map[String, String]) extends LogicalPlan with RunnableCommand with Product with Serializable

   

5. case class CreateTempTableUsingAsSelect(tableIdent: TableIdentifier, provider: String, partitionColumns: Array[String], mode: SaveMode, options: Map[String, String], query: LogicalPlan) extends LogicalPlan with RunnableCommand with Product with Serializable

   

6. class DDLException extends RuntimeException

   

   The exception thrown from the DDL parser.

7. class DDLParser extends AbstractSparkSQLParser with DataTypeParser with Logging

   

   A parser for foreign DDL commands.

8. class DefaultSource extends RelationProvider with DataSourceRegister

   

9. case class DescribeCommand(table: LogicalPlan, isExtended: Boolean) extends LogicalPlan with 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.

10. case class RefreshTable(tableIdent: TableIdentifier) extends LogicalPlan with RunnableCommand with Product with Serializable

    

11. case class ResolvedDataSource(provider: Class[_], relation: BaseRelation) extends Product with Serializable
