Struct PlanDiff 

pub struct PlanDiff {
    pub added: Vec<String>,
    pub removed: Vec<String>,
    pub changed: Vec<String>,
}

Summary of structural differences between two physical plans.

Used by operators to understand what changed between two versions of the same job’s physical plan (e.g. after an adaptive repartitioning decision in R7/R9).

Fields

added: Vec<String>

Node ids present in after but not in before.

removed: Vec<String>

Node ids present in before but not in after.

changed: Vec<String>

Node ids present in both plans but with different labels or operators.

Implementations
