  3. abstract def generate(inputBatch: ColumnarBatch, generatorOffset: Int, outer: Boolean): ColumnarBatch

    Apply generator to produce result ColumnarBatch from input batch.

    Apply generator to produce result ColumnarBatch from input batch.

    This is a specialized method for GPU runtime, which is called by GpuGenerateExec who owns the generator. The reason of creating a new method rather than implementing columnarEval is that generator is an integrated Table transformer instead of column transformer in terms of cuDF.

    inputBatch

    projected input data, which ensures appending columns are ahead of generators' inputs. So, generators can distinguish them with an offset.

    generatorOffset

    column offset of generator's input columns in inputBatch

    outer

    when true, each input row will be output at least once, even if the output of the given generator is empty.

    returns

    result ColumnarBatch

  20. final def columnarEval(batch: ColumnarBatch): Any

    Returns the result of evaluating this expression on the entire ColumnarBatch.

    Returns the result of evaluating this expression on the entire ColumnarBatch. The result of calling this may be a single GpuColumnVector or a scalar value. Scalar values typically happen if they are a part of the expression i.e. col("a") + 100. In this case the 100 is a literal that Add would have to be able to handle.

    By convention any GpuColumnVector returned by columnarEval is owned by the caller and will need to be closed by them. This can happen by putting it into a ColumnarBatch and closing the batch or by closing the vector directly if it is a temporary value.

    Override this if your expression cannot allow combining of data from multiple files into a single batch before it operates on them. These are for things like getting the input file name. Which for spark is stored in a thread local variable which means we have to jump through some hoops to make this work.

    Extract lazy expressions from generator if exists.

    This is a specialized method for GPU runtime, which is called by GpuGenerateExec to determine whether current generation plan can be executed with optimized lazy array generation or not.

    returns

    fixed length lazy expressions for generation. Nil value means no lazy expressions to extract, which indicates fixed length lazy array generation is unavailable.

    Compute split indices for generator's input batches.

    Compute split indices for generator's input batches.

    This is a specialized method for GPU runtime, which is called by GpuGenerateExec to split up input batches to reduce total memory cost during generating. It is necessary because most of generators may produce multiple records for each input record, which make output batch size much larger than input size.

    inputBatch

    projected input data, which ensures appending columns are ahead of generators' inputs. So, generators can distinguish them with an offset.

    generatorOffset

    column offset of generator's input columns in inputBatch

    outer

    when true, each input row will be output at least once, even if the output of the given generator is empty.

    targetSizeBytes

    the target number of bytes for a GPU batch, one of RapidsConf

    returns

    split indices of input batch
