   @richardstartin @Jackie-Jiang Yes I have done some experiments with `BufferFastAggregation.and` https://github.com/apache/pinot/pull/9370. However, it didn't give very promising results:
   - using BufferFastAggregation alone without sorting yields an 1.1x speedup while 60% overhead in degenerate case
   - sorting on top of this gives marginal speedup
