Struct DistributedJoinRule 

Source 
pub struct DistributedJoinRule;
Expand description

Physical optimizer rule that wraps HashJoinExec inputs in ClusterRepartitionExec.

Trait Implementations§

Source§

impl Debug for DistributedJoinRule

Source§

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

Formats the value using the given formatter. Read more
Source§

impl PhysicalOptimizerRule for DistributedJoinRule

Available on crate feature cluster only.
Source§

fn optimize( &self, plan: Arc<dyn ExecutionPlan>, _config: &ConfigOptions, ) -> Result<Arc<dyn ExecutionPlan>>

Rewrite plan to an optimized form
Source§

fn name(&self) -> &'static str

A human readable name for this optimizer rule
Source§

fn schema_check(&self) -> bool

A flag to indicate whether the physical planner should validate that the rule will not change the schema of the plan after the rewriting. Some of the optimization rules might change the nullable properties of the schema and should disable the schema check.
