Struct mz_dataflow::EventLinkBoundary

source · [−]

pub struct EventLinkBoundary {
    shared: BTreeMap<(Uuid, GlobalId), SourceBoundary>,
    requests: UnboundedSender<SourceInstanceRequest<u64>>,
}

Expand description

A simple boundary that uses activated event linked lists.

Fields

shared: BTreeMap<(Uuid, GlobalId), SourceBoundary>

Source boundaries shared between storage and compute.

requests: UnboundedSender<SourceInstanceRequest<u64>>

Enqueue source rendering requests.

Implementations
