Enum OptimizationPhase 

pub enum OptimizationPhase {
    Rewrite,
    Logical,
    Physical,
    Unknown,
}

Optimization phase - used to optimize rule classification

Indicates the phase to which the optimization rule belongs and is used to control the order in which the rule is executed.

Variants

Rewrite

Rewrite Phase - Logical Rewrite Rules

Logical

Logic Optimization Phase - Logic Plan Optimization

Physical

Physical Optimization Phase - Physical Plan Optimization

Unknown

unknown stage
