19.  def setupForJoin(queue: Queue[ColumnarBatch], remainingIter: Iterator[ColumnarBatch], batchTypes: Array[DataType], gpuBatchSizeBytes: Long, metrics: Map[String, GpuMetric]): Iterator[ColumnarBatch]

    Build an iterator in preparation for using it for sub-joins.

    Build an iterator in preparation for using it for sub-joins.

    queue

    a possibly empty queue of data that has already been fetched from the underlying iterator as part of probing sizes of the join inputs

    remainingIter

    the data remaining to be fetched from the original iterator. Iterating the queue followed by this iterator reconstructs the iteration order of the original input iterator.

    batchTypes

    the schema of the data

    gpuBatchSizeBytes

    target GPU batch size in bytes

    metrics

    metrics to update (e.g.: if coalescing batches)

    returns

    iterator of columnar batches to use in sub-joins
