Enum Origin 

pub enum Origin {
    Computed {
        node_id: String,
        run_id: String,
    },
    Ingested {
        source: String,
    },
    Streamed {
        window_start: DateTime<Utc>,
        window_end: DateTime<Utc>,
    },
}

Where a cached value originated.

Variants

Computed

Produced by executing a node — the common case.

Fields

node_id: String

Node that produced the value.

run_id: String

Run the computation happened in.

Ingested

Loaded from an external source rather than computed.

Fields

source: String

Where the value came from (path, URL, dataset name).

Streamed

Produced by a stream executor over a time window.

Fields

window_start: DateTime<Utc>

Inclusive start of the window.

window_end: DateTime<Utc>

Exclusive end of the window.
