  22. 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.

    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

    These are values that spark calls initial because it uses them to initialize the aggregation buffer, and returns them in case of an empty aggregate when there are no expressions.

    In our case they are only used in a very specific case: the empty input reduction case. In this case we don't have input to reduce, but we do have reduction functions, so each reduction function's initialValues is invoked to populate a single row of output.

    merge: second half of the aggregation. Also used to merge multiple batches in the update or merge stages. These cuDF aggregates consume the output of preMerge. The sequence of CudfAggregate must match the shape of aggBufferAttributes, and care must be taken to ensure that each cuDF aggregate is able to work with the corresponding input (i.e. aggBufferAttributes[i] is the input to mergeAggregates[i]). If a transformation is required, preMerge can be used to mutate the batches before they arrive at mergeAggregates.

  87. final lazy val postMergeAttr: Seq[AttributeReference]

    This is the last aggregation step, which optionally changes the result of the mergeAggregate.

    This is the last aggregation step, which optionally changes the result of the mergeAggregate. postMergeAttr: matches the order (and types) of mergeAggregates postMerge: binds to postMergeAttr and defines an expression that results in what Spark expects from the merge. We set this to postMergeAttr by default, for the pass through case (like in postUpdate). GpuM2 is the exception, where postMerge mutates the result of the mergeAggregates to output what Spark expects.

    This is the last step in the update phase.

    This is the last step in the update phase. It can optionally modify the result of the cuDF update aggregates, or be a pass-through. postUpdateAttr: matches the order (and types) of updateAggregates postUpdate: binds to postUpdateAttr and defines an expression that results in what Spark expects from the update. By default this is postUpdateAttr, as it should match the shape of the Spark agg buffer leaving cuDF, but in the M2 and Count cases we overwrite it, because the cuDF shape isn't what Spark expects.

    This step is the first step into the merge phase. It can optionally modify the result of the postUpdate before it goes into the cuDF merge aggregation. preMerge: modify a partial batch to match the input required by a merge aggregate

    This always binds to aggBufferAttributes as that is the inbound schema for this aggregate from Spark. If it is set to aggBufferAttributes by default so the bind behaves like a pass through in most cases.
