Review Comment: The experimental Dense Vector Search under development in Lucene (and Solr consequentially) is expected to change a lot in this phase. There have been many changes both in Lucene 9.1.0 and in the upcoming 9.2.0. Some of these changes are backed by a new codec effectively, so it's a delicate balance. When features are marked as "Experimental" is it acceptable to make it simple and just require people to re-index(of course only if they use a vector-based field)? That codec param is going away soon anyway(we'll submit a PR after this for that), as it's preferable to give the user the ability to just choose the algorithm (currently only HNSW supported) rather than the internal codec. @msokolov , @mocobeta what do you think? Thanks @madrob for raising this, it's definitely something we need to discuss! -- This is an automated message from the Apache Git Service.
