• Table (LogicalPlan)
• Partition Specification (Map[String, Option[String]])
• User-specified column names
• Query
• overwrite flag
• ifPartitionNotExists flag

• Catalyst DSL is used to insertInto
• AstBuilder is requested to withInsertInto
• DataFrameWriter is requested to insertInto

Logical Resolution¶

InsertIntoStatement is resolved to the following logical operators:

• InsertIntoDataSourceCommand (for InsertIntoStatements over LogicalRelation over InsertableRelation) by DataSourceAnalysis
• InsertIntoHadoopFsRelationCommand (for InsertIntoStatements over LogicalRelation over HadoopFsRelation) by DataSourceAnalysis

Logical Analysis¶

InsertIntoStatements with UnresolvedCatalogRelations are resolved by the following logical analysis rules:

• FindDataSourceTable
• FallBackFileSourceV2
• PreprocessTableInsertion
• PreWriteCheck
