Struct ExtractionMetadata 

Source 
pub struct ExtractionMetadata {
    pub strategy: String,
    pub cursor_column: Option<String>,
    pub cursor_type: Option<String>,
    pub cursor_low: Option<String>,
    pub cursor_high: Option<String>,
    pub source_row_count: Option<i64>,
}
Expand description

Cursor/strategy metadata shipped in the manifest for warehouse-side reconciliation. Cursor bounds are STRING-encoded and type-tagged: a lexical order lies on numbers (the same trap as a binlog __pos string), so the consumer compares by cursor_type, not by raw string order.

Fields§

§strategy: String

full / incremental / chunked / keyset / timewindow.

§cursor_column: Option<String>

Resolved cursor/key column, when the strategy has one.

§cursor_type: Option<String>

Source type of the cursor column (for typed range comparison).

§cursor_low: Option<String>

Lowest cursor value covered by THIS extract (the prior run’s high, or the min seen this run). None for a full snapshot / first run.

§cursor_high: Option<String>

Highest cursor value covered — the value the NEXT run must resume from.

§source_row_count: Option<i64>

Source-side row count at extraction time, when cheaply known — distinct from the manifest’s row_count (rows EXTRACTED). A divergence is the reconciliation signal. None when not probed.
