  37. def pruneColumns(scanBuilder: ScanBuilder, relation: DataSourceV2Relation, projects: Seq[NamedExpression], filters: Seq[Expression]): (Scan, Seq[AttributeReference])

    Applies column pruning to the data source, w.r.t.

    Applies column pruning to the data source, w.r.t. the references of the given expressions.

    returns

    the Scan instance (since column pruning is the last step of operator pushdown), and new output attributes after column pruning.

  38. def pushFilters(scanBuilder: ScanBuilder, filters: Seq[Expression]): (Seq[Filter], Seq[Expression])

    Pushes down filters to the data source reader

    Pushes down filters to the data source reader

    returns

    pushed filter and post-scan filters.
