Struct DistributedPlan 

pub struct DistributedPlan {
    pub query_id: QueryId,
    pub metadata_version: MetadataVersion,
    pub fragments: Vec<PlanFragment>,
    pub exchanges: Vec<ExchangeDescriptor>,
}

A distributed query plan pinned to one control-plane metadata version (spec section 12.10).

Fields

query_id: QueryId

The query execution this plan belongs to.

metadata_version: MetadataVersion

The control-plane metadata version the plan was built against.

fragments: Vec<PlanFragment>

All fragments; fragment_id equals the vector index.

exchanges: Vec<ExchangeDescriptor>

All exchange edges; exchange_id equals the vector index.

Implementations

impl DistributedPlan

pub fn root_fragment_id(&self) -> Option<FragmentId>

The fragment with no outgoing exchange (the coordinator root).

pub fn fragment(&self, fragment_id: FragmentId) -> Option<&PlanFragment>

Looks up a fragment by id.

pub fn exchanges_from( &self, producer: FragmentId, ) -> impl Iterator<Item = &ExchangeDescriptor>

Exchange edges out of one fragment.

pub fn exchanges_into(&self, consumer: FragmentId) -> Vec<&ExchangeDescriptor>

Exchange edges into one fragment, ordered by producer id.
