source§fn as_any(&self) -> &dyn Any
fn as_any(&self) -> &dyn Any
Returns the execution plan as
Any
so that it can be
downcast to a specific implementation.source§fn output_partitioning(&self) -> Partitioning
fn output_partitioning(&self) -> Partitioning
Specifies the output partitioning scheme of this plan
source§fn unbounded_output(&self, _children: &[bool]) -> Result<bool>
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.
source§fn output_ordering(&self) -> Option<&[PhysicalSortExpr]>
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. Read moresource§fn children(&self) -> Vec<Arc<dyn ExecutionPlan>>
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).
source§fn with_new_children(
self: Arc<Self>,
_: Vec<Arc<dyn ExecutionPlan>>
) -> Result<Arc<dyn ExecutionPlan>>
fn with_new_children( self: Arc<Self>, _: Vec<Arc<dyn ExecutionPlan>> ) -> Result<Arc<dyn ExecutionPlan>>
Returns a new plan where all children were replaced by new plans.

&self,
_partition: usize,
_context: Arc<TaskContext>
) -> Result<SendableRecordBatchStream>
fn execute( &self, _partition: usize, _context: Arc<TaskContext> ) -> Result<SendableRecordBatchStream>
creates an iterator

fn statistics(&self) -> Statistics
Returns the global output statistics for this

node.source§fn required_input_distribution(&self) -> Vec<Distribution>
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,
source§fn required_input_ordering(&self) -> Vec<Option<Vec<PhysicalSortRequirement>>>
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 Read more
source§fn maintains_input_order(&self) -> Vec<bool>
fn maintains_input_order(&self) -> Vec<bool>
Returns
false
if this operator’s implementation may reorder
rows within or between partitions. Read moresource§fn benefits_from_input_partitioning(&self) -> bool
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 Read moresource§fn equivalence_properties(&self) -> EquivalenceProperties
fn equivalence_properties(&self) -> EquivalenceProperties
Get the EquivalenceProperties within the plan

fn ordering_equivalence_properties(&self) -> OrderingEquivalenceProperties
Get the OrderingEquivalenceProperties within the plan
