GpuLessThan

case class GpuLessThan(left: Expression, right: Expression) extends CudfBinaryComparison with NullIntolerant with Product with Serializable

The table below shows how the result is calculated for Less-than. To make calculation easier we are leveraging the fact that the cudf-result(r) always returns false. So that result is used in place of false when needed.

In this case return !lhs.nan && rhs.nan || result[i]

+-------------+------------+-----------------+---------------+-----+ | lhs.isNan()| rhs.isNan | cudf-result(r) | final-result | lt | +-------------+------------+-----------------+---------------+-----+ | t | f | f | r | f | | f | t | f | t | t | | t | t | f | r | f | | f | f | r | r | NA | +-------------+------------+-----------------+---------------+-----+

  24. 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.

    Build an equivalent representation of this expression in a cudf AST.

    numFirstTableColumns

    number of columns in the leftmost input table. Spark places the columns of all inputs in a single sequence, while cudf AST uses an explicit table reference to make column indices unique. This parameter helps translate input column references from Spark's single sequence into cudf's separate sequences.

    returns

    top node of the equivalent AST

    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.
