Enum PrunePredicate 

pub enum PrunePredicate {
    And(Vec<PrunePredicate>),
    Or(Vec<PrunePredicate>),
    Compare {
        column: String,
        op: PruneOp,
        value: PruneValue,
    },
    In {
        column: String,
        values: Vec<PruneValue>,
    },
    Opaque,
}

Simplified predicate tree the planner hands to the pruner. Only the shapes we can actually act on are named; anything else the planner tags Opaque, which keeps every partition.

Variants

And(Vec<PrunePredicate>)

Or(Vec<PrunePredicate>)

Compare

column op value.

Fields

column: String

op: PruneOp

value: PruneValue

In

column IN (v1, v2, …).

Fields

column: String

values: Vec<PruneValue>

Opaque

Something we can’t interpret. Acts as “every row possibly matches” for pruning purposes.
