Expand description
Unnest a column that contains a nested list type. See
UnnestOptions
for more details.
Fields§
§input: Arc<LogicalPlan>
The incoming logical plan
exec_columns: Vec<Column>
Columns to run unnest on, can be a list of (List/Struct) columns
list_type_columns: Vec<(usize, ColumnUnnestList)>
refer to the indices(in the input schema) of columns that have type list to run unnest on
struct_type_columns: Vec<usize>
refer to the indices (in the input schema) of columns that have type struct to run unnest on
dependency_indices: Vec<usize>
Having items aligned with the output columns representing which column in the input schema each output column depends on
schema: DFSchemaRef
The output schema, containing the unnested field column.
options: UnnestOptions
