Class ColumnarRowView

java.lang.Object
com.databricks.jdbc.api.impl.ColumnarRowView
public class ColumnarRowView extends Object
Memory-efficient columnar view that provides row-based access without materializing all rows. Instead of creating Listinvalid input: '<'List>, this class provides direct access to columnar data on a per-row, per-column basis, significantly reducing memory allocations.
