Struct datafusion::physical_plan::insert::InsertExec

pub struct InsertExec { /* private fields */ }

Execution plan for writing record batches to a DataSink

Returns a single row with the number of values written

Implementations

impl InsertExec

pub fn new(input: Arc<dyn ExecutionPlan>, sink: Arc<dyn DataSink>) -> Self

Create a plan to write to sink

Trait Implementations

impl Debug for InsertExec

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl ExecutionPlan for InsertExec

fn as_any(&self) -> &dyn Any

Return a reference to Any that can be used for downcasting

fn schema(&self) -> SchemaRef

Get the schema for this execution plan

fn execute( &self, partition: usize, context: Arc<TaskContext> ) -> Result<SendableRecordBatchStream>

Execute the plan and return a stream of RecordBatches for the specified partition.

fn output_partitioning(&self) -> Partitioning

Specifies the output partitioning scheme of this plan

fn output_ordering(&self) -> Option<&[PhysicalSortExpr]>

If the output of this operator within each partition is sorted, returns Some(keys) with the description of how it was sorted.

fn required_input_distribution(&self) -> Vec<Distribution>

Specifies the data distribution requirements for all the children for this operator, By default it’s [Distribution::UnspecifiedDistribution] for each child,

fn required_input_ordering(&self) -> Vec<Option<Vec<PhysicalSortRequirement>>>

Specifies the ordering requirements for all of the children For each child, it’s the local ordering requirement within each partition rather than the global ordering

fn maintains_input_order(&self) -> Vec<bool>

Returns false if this operator’s implementation may reorder rows within or between partitions.

fn children(&self) -> Vec<Arc<dyn ExecutionPlan>>

Get a list of child execution plans that provide the input for this plan. The returned list will be empty for leaf nodes, will contain a single value for unary nodes, or two values for binary nodes (such as joins).

fn with_new_children( self: Arc<Self>, children: Vec<Arc<dyn ExecutionPlan>> ) -> Result<Arc<dyn ExecutionPlan>>

Returns a new plan where all children were replaced by new plans.

fn fmt_as(&self, t: DisplayFormatType, f: &mut Formatter<'_>) -> Result

Format this ExecutionPlan to f in the specified type.

fn statistics(&self) -> Statistics

Returns the global output statistics for this ExecutionPlan node.

fn unbounded_output(&self, _children: &[bool]) -> Result<bool>

Specifies whether this plan generates an infinite stream of records. If the plan does not support pipelining, but its input(s) are infinite, returns an error to indicate this.

fn benefits_from_input_partitioning(&self) -> bool

Returns true if this operator would benefit from partitioning its input (and thus from more parallelism). For operators that do very little work the overhead of extra parallelism may outweigh any benefits

fn equivalence_properties(&self) -> EquivalenceProperties

Get the EquivalenceProperties within the plan

fn ordering_equivalence_properties(&self) -> OrderingEquivalenceProperties

Get the OrderingEquivalenceProperties within the plan

fn metrics(&self) -> Option<MetricsSet>

Return a snapshot of the set of Metrics for this ExecutionPlan.
