  2. abstract def createGatherer(cb: ColumnarBatch, numJoinRows: Option[Long]): Option[JoinGatherer]

    Create a join gatherer.

    Create a join gatherer.

    cb

    next column batch from the streaming side of the join

    numJoinRows

    if present, the number of join output rows computed for this batch

    returns

    Called to setup the next join gatherer instance when the previous instance is done or there is no previous instance. Because this is likely to call next or has next on the stream side all implementations must track their own opTime metrics.

    returns

    some gatherer to use next or None if there is no next gatherer or the loop should try to build the gatherer again (e.g.: to skip a degenerate join result batch)
