Struct mz_dataflow_types::plan::join::delta_join::DeltaJoinPlan
source · [−]pub struct DeltaJoinPlan {
pub path_plans: Vec<DeltaPathPlan>,
}
Expand description
A delta query is implemented by a set of paths, one for each input.
Each delta query path responds to its input changes by repeated lookups in arrangements for other join inputs. These lookups require specific instructions about which expressions to use as keys. Along the way, various closures are applied to filter and project as early as possible.
Fields
path_plans: Vec<DeltaPathPlan>
The set of path plans.
Each path identifies its source relation, so the order is only important for determinism of dataflow construction.
