We can only write index with lucene99 based codecs? True, after upgrading Lucece to 0.9.10, we can only write an index based on lucene99. > 2. If a new generated index is served by an old server (running Lucene 9.8.0), will it break? I am unsure, but I will say it will break if I have to guess. The only thing is this vector functionality (classes) got added in Pinot on Dec/23, so I am not sure how much it is getting used. Maybe @xiangfu0 can help us here with a better understanding. -- This is an automated message from the Apache Git Service.
