pub fn meta_column_specs(warehouse: Warehouse) -> Vec<TargetColumnSpec>Expand description
The three CDC meta columns rivet’s change log carries, typed for
warehouse. rivet CDC writes __op (Utf8), __pos (Utf8), __seq (Int64)
ahead of the after-image columns (OSS cdc::sink); rivet check reports
only the data columns, so the loader must prepend these to build the
<table>__changes schema.
