CopyBatch copies the original batch and returns that copy.

NewRandomDataOp creates a new randomDataOp.

RandomBatch returns a batch with a capacity of capacity and a number of random elements equal to length (capacity if length is 0).

RandomBatchWithSel is equivalent to RandomBatch, but will also add a selection vector to the batch where each row is selected with probability selProbability.

RandomSel creates a random selection vector up to a given batchSize in length.

RandomVec populates vector with random values, setting each value to null with the given probability.

RandomDataOpArgs are arguments passed in to randomDataOp.

RandomVecArgs is a utility struct that contains arguments to RandomVec call.
