Struct datafusion::physical_plan::test::exec::PanicExec
source · pub struct PanicExec { /* private fields */ }
Expand description
Execution plan that emits streams that panics.
This is useful to test panic handling of certain execution plans.
Implementations§
source§impl PanicExec
impl PanicExec
sourcepub fn new(schema: Arc<Schema>, n_partitions: usize) -> PanicExec
pub fn new(schema: Arc<Schema>, n_partitions: usize) -> PanicExec
Create new PanicExec
with a give schema and number of
partitions, which will each panic immediately.
sourcepub fn with_partition_panic(self, partition: usize, count: usize) -> PanicExec
pub fn with_partition_panic(self, partition: usize, count: usize) -> PanicExec
Set the number of batches prior to panic for a partition

source§fn as_any(&self) -> &(dyn Any + 'static)
fn as_any(&self) -> &(dyn Any + 'static)
Returns the execution plan as
Any
so that it can be
downcast to a specific implementation.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 with_new_children(
self: Arc<PanicExec>,
_: Vec<Arc<dyn ExecutionPlan>>,
) -> Result<Arc<dyn ExecutionPlan>, DataFusionError>
fn with_new_children( self: Arc<PanicExec>, _: 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>

source§fn name(&self) -> &'static strwhere
Self: Sized,
fn name(&self) -> &'static strwhere
Self: Sized,
Short name for the ExecutionPlan, such as ‘ParquetExec’.
source§fn static_name() -> &'static strwhere
Self: Sized,
fn static_name() -> &'static strwhere
Self: Sized,
Short name for the ExecutionPlan, such as ‘ParquetExec’.
Like
name
but can be called without an instance.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 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 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 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 moresource§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.Auto Trait Implementations§
