class ChunkedPacker extends Iterator[MemoryBuffer] with Logging with AutoCloseable

ChunkedPacker is an Iterator that uses a cudf::chunked_pack to copy a cuDF Table to a target buffer in chunks.

Each chunk is sized at most bounceBuffer.getLength, and the caller should cudaMemcpy bytes from bounceBuffer to a target buffer after each call to next().

Note

ChunkedPacker must be closed by the caller as it has GPU and host resources associated with it.

Instance Constructors

  1. new ChunkedPacker(id: RapidsBufferId, table: Table, bounceBuffer: DeviceMemoryBuffer)

    id

    The RapidsBufferId for this pack operation to be included in the metadata

    table

    cuDF Table to chunk_pack

    bounceBuffer

    GPU memory to be used for packing. The buffer should be at least 1MB in length.
