Struct PhysicalMerge

pub struct PhysicalMerge {
    pub table_name: String,
    pub table_id: u64,
    pub properties: Vec<(String, Expression)>,
    pub on_match: Vec<PhysicalSet>,
    pub on_create: Vec<PhysicalSet>,
    pub table_catalog: Arc<TableCatalog>,

}

Expand description

Physical operator for MERGE. Represents a combination of MATCH and INSERT (Upsert).

Fields§

§table_name: String§table_id: u64§properties: Vec<(String, Expression)>§on_match: Vec<PhysicalSet>§on_create: Vec<PhysicalSet>§table_catalog: Arc<TableCatalog>§txn_id: Option<u64>

Active transaction id (P52.18).

§undo_sink: Option<Arc<Mutex<Vec<UndoRecord>>>>

Undo sink for rollback records (P52.18).

§wal_sink: Option<WalSink>

Typed WAL sink so MERGE-created rows survive restarts via replay (P60.2).

where T: Any,

Source §

fn into_any(self: Box<T>) -> Box<dyn Any>

Converts Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>, which can then be downcast into Box<dyn ConcreteType> where ConcreteType implements Trait.
