> @lpld quantizing is done per segment, at flush and merge time. So it takes into account live vectors in the segment during flush and merge. > > I don't see why adding/updating/deleting would be any issue And also, Lucene retains the full precision original (`float[]`) vectors, so that even during segment merging, the quantization is recomputed (accurately) from the original vectors. There have been some issues/discussions about somehow not keeping the original vectors (they are costly in index storage, and lead to complications like [skipping them when replicating an index that will be used only for searching](https://github.com/apache/lucene/issues/13158)), but so far those have not been implemented (I think?). -- This is an automated message from the Apache Git Service.
