@Jackie-Jiang it depends. Constructing bitmaps from unordered values is inefficient, and in general there's no point in using `RoaringBitmapWriter`, so if the dictionary ids have a very large range this won't help much, but if the cardinality is less than the 2^16 this particular configuration will work very well because all the adds will be buffered into a small bitset, regardless of order. It's not clear to me how helpful this will be with unordered data with very high range though. -- This is an automated message from the Apache Git Service.
