source§fn as_any(&self) -> &(dyn Any + 'static)
fn as_any(&self) -> &(dyn Any + 'static)
Return a reference to Any that can be used for downcasting
source§fn properties(&self) -> &PlanProperties
fn properties(&self) -> &PlanProperties
Return properties of the output of the
ExecutionPlan
, such as output
ordering(s), partitioning information etc. Read moresource§fn children(&self) -> Vec<Arc<dyn ExecutionPlan>>
fn children(&self) -> Vec<Arc<dyn ExecutionPlan>>
Get a list of children
ExecutionPlan
s that act as inputs to this plan.
The returned list will be empty for leaf nodes such as scans, will contain
a single value for unary nodes, or two values for binary nodes (such as
joins).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
ExecutionPlan
, By default it’s [Distribution::UnspecifiedDistribution] for each child,source§fn maintains_input_order(&self) -> Vec<bool>
fn maintains_input_order(&self) -> Vec<bool>
Returns
false
if this ExecutionPlan
’s implementation may reorder
rows within or between partitions. Read moresource§fn benefits_from_input_partitioning(&self) -> Vec<bool>
fn benefits_from_input_partitioning(&self) -> Vec<bool>
Specifies whether the
ExecutionPlan
benefits from increased
parallelization at its input for each child. Read moresource§fn with_new_children(
self: Arc<GlobalLimitExec>,
children: Vec<Arc<dyn ExecutionPlan>>
) -> Result<Arc<dyn ExecutionPlan>, DataFusionError>
fn with_new_children( self: Arc<GlobalLimitExec>, children: Vec<Arc<dyn ExecutionPlan>> ) -> Result<Arc<dyn ExecutionPlan>, DataFusionError>
Returns a new
ExecutionPlan
where all existing children were replaced
by the children
, in ordersource§fn execute(
&self,
partition: usize,
context: Arc<TaskContext>
) -> Result<Pin<Box<dyn RecordBatchStream<Item = Result<RecordBatch, DataFusionError>> + Send>>, DataFusionError>
fn execute( &self, partition: usize, context: Arc<TaskContext> ) -> Result<Pin<Box<dyn RecordBatchStream<Item = Result<RecordBatch, DataFusionError>> + Send>>, DataFusionError>
source§fn metrics(&self) -> Option<MetricsSet>
fn metrics(&self) -> Option<MetricsSet>
Return a snapshot of the set of
Metric
s for this
ExecutionPlan
. If no Metric
s are available, return None. Read moresource§fn statistics(&self) -> Result<Statistics, DataFusionError>
fn statistics(&self) -> Result<Statistics, DataFusionError>
Returns statistics for this
ExecutionPlan
node. If statistics are not
available, should return Statistics::new_unknown
(the default), not
an error.source§fn required_input_ordering(&self) -> Vec<Option<Vec<PhysicalSortRequirement>>>
fn required_input_ordering(&self) -> Vec<Option<Vec<PhysicalSortRequirement>>>
Specifies the ordering required for all of the children of this
ExecutionPlan
. Read moresource§fn repartitioned(
&self,
_target_partitions: usize,
_config: &ConfigOptions
) -> Result<Option<Arc<dyn ExecutionPlan>>, DataFusionError>
fn repartitioned( &self, _target_partitions: usize, _config: &ConfigOptions ) -> Result<Option<Arc<dyn ExecutionPlan>>, DataFusionError>
If supported, attempt to increase the partitioning of this
ExecutionPlan
to
produce target_partitions
partitions. Read moreAuto Trait Implementations§
