@benwtrent Can you please help me understand the following: 1. In terms of quantization, are we doing any extra processing for 4 and 7 bits when compared to 8 bits ? I believe not. 2. For 7 bits, how are we reducing memory usage compared to 8 bits. Are we doing any extra compression somewhere. Am I missing something ? 3. For 4 bits, should we must set `compress` flag to `True` to [reduce the memory usage by about 50% ](https://github.com/apache/lucene/blob/main/lucene/core/src/java/org/apache/lucene/codecs/lucene99/OffHeapQuantizedByteVectorValues.java#L72-L89)(theoretically) compared to 8 bits ? -- This is an automated message from the Apache Git Service.
