Struct PartialMatch 

Source 
pub struct PartialMatch {
    pub stage_index: usize,
    pub captured_events: Vec<RecordBatch>,
    pub start_time_ms: i64,
    pub captured_event_count: usize,
}
Expand description

Partial in-progress match.

The captured_events field is the live, in-memory list of record batches that have matched stages so far. The persistence-friendly companion fields (stage_index, captured_event_count, start_time_ms) can be serialised and snapshotted by the checkpoint coordinator; the executor is expected to keep captured_events in a separate durable store (or replay from the source on restart) so that the metadata in the checkpoint is sufficient to reconstruct the partial match.

Fields§

§stage_index: usize§captured_events: Vec<RecordBatch>§start_time_ms: i64§captured_event_count: usize

Number of events captured so far; mirrors captured_events.len() so the field can be serialised by the checkpoint coordinator (the actual RecordBatch payloads live in a separate durable store keyed by this count). Kept in sync by process_event.
