Expand description

State maintained by the write operator.

Fields§

§worker_id: usize§persist_writer: WriteHandle<SourceData, (), Timestamp, Diff>§corrections: OkErr<Correction<Row>, Correction<DataflowError>>

Contains desired - persist, reflecting the updates we would like to commit to persist in order to “correct” it to track desired. This collection is only modified by updates received from either the desired or persist inputs.

§desired_frontiers: OkErr<Antichain<Timestamp>, Antichain<Timestamp>>

The frontiers of the desired inputs.

§persist_frontiers: OkErr<Antichain<Timestamp>, Antichain<Timestamp>>

The frontiers of the persist inputs.

§batch_description: Option<(BatchDescription, Capability<Timestamp>)>

The current valid batch description and associated output capability, if any.
