> Data of different channels can be appended to a SortBuffer and after the SortBuffer is finished, the appended data can be copied from it in channel index order. PartitionSortedBuffer is an implementation of SortBuffer and it sorts all appended records only by subpartition index. Records of the same subpartition keep the appended order.
