GpuPackedTableColumn

final class GpuPackedTableColumn extends GpuColumnVectorBase with WithTableBuffer

A GPU column tracking a packed table such as one generated by contiguous split. Unlike GpuColumnVectorFromBuffer, the columnar data cannot be accessed directly.

This class primarily serves the role of tracking the packed table data in a ColumnarBatch without requiring the underlying table to be manifested along with all of the child columns. The typical use-case generates one of these columns per task output partition, and then the RAPIDS shuffle transmits the opaque host metadata and GPU data buffer to another host.

NOTE: There should only be one instance of this column per ColumnarBatch as the
