Struct deltalake::datafusion::physical_plan::display::DisplayableExecutionPlan

pub struct DisplayableExecutionPlan<'a> { /* private fields */ }

Wraps an ExecutionPlan with various ways to display this plan

Implementations

impl<'a> DisplayableExecutionPlan<'a>

pub fn new(inner: &'a dyn ExecutionPlan) -> DisplayableExecutionPlan<'a>

Create a wrapper around an ExecutionPlan which can be pretty printed in a variety of ways

pub fn with_metrics( inner: &'a dyn ExecutionPlan ) -> DisplayableExecutionPlan<'a>

Create a wrapper around an ExecutionPlan which can be pretty printed in a variety of ways that also shows aggregated metrics

pub fn with_full_metrics( inner: &'a dyn ExecutionPlan ) -> DisplayableExecutionPlan<'a>

Create a wrapper around an ExecutionPlan which can be pretty printed in a variety of ways that also shows all low level metrics

pub fn set_show_statistics( self, show_statistics: bool ) -> DisplayableExecutionPlan<'a>

Enable display of statistics

pub fn indent(&self, verbose: bool) -> impl Display + 'a

Return a formatable structure that produces a single line per node.

ProjectionExec: expr=[a]
  CoalesceBatchesExec: target_batch_size=8192
    FilterExec: a < 5
      RepartitionExec: partitioning=RoundRobinBatch(16)
        CsvExec: source=...",

pub fn graphviz(&self) -> impl Display + 'a

Returns a formatable structure that produces graphviz format for execution plan, which can be directly visualized here.

An example is

strict digraph dot_plan {

pub fn one_line(&self) -> impl Display + 'a

Return a single-line summary of the root of the plan Example: ProjectionExec: expr=[a@0 as a].

pub fn to_stringified( &self, verbose: bool, plan_type: PlanType ) -> StringifiedPlan

format as a StringifiedPlan
