### Description Today, float vectors are [aligned to 4 bytes](https://github.com/apache/lucene/blob/8e8e37d9e94c290cf8d02e9f318e601baedf28bc/lucene/core/src/java/org/apache/lucene/codecs/lucene99/Lucene99FlatVectorsWriter.java#L205) in a Lucene index, but with Panama -- we can work with (upto) 512 bits (== 64 bytes, or 16 floats) at the same time. I wonder if we should change this alignment to 64 bytes, in order to get optimal vector search performance with Panama? -- This is an automated message from the Apache Git Service.
