Struct BackfillStateWithProgress

source 
pub struct BackfillStateWithProgress {
    pub state: BackfillState,
    pub num_consumed_rows: u64,
    pub target_offset: Option<String>,
}
Expand description

Only state field is the real state for fail-over. Other fields are for observability (but we still need to persist them).

Fields§

§state: BackfillState§num_consumed_rows: u64§target_offset: Option<String>

The latest offset from upstream (inclusive). After we reach this offset, we can stop backfilling. This is initialized with the latest available offset in the connector (if the connector provides the ability to fetch it) so that we can finish backfilling even when upstream doesn’t emit any data.
