------------------------------------------------------------------

Thanks [~alangates] for looking into it. So, we begin with {{ROW__ID}} in sort and shuffle
key and partition column as value of RS. In this optimization if we change RS sort and shuffle
key to ROW__ID and partition column, we need not to keep orc buffer open and thus avoid OOM
case. But is that ok with ACID writer in FileSink or it assumes sort and shuffle keys as {{ROW__ID}}
and nothing else?
