Tomoko Uchida commented on LUCENE-9855:
---------------------------------------
So... I would like to return to the main point here. It's a blocker for 9.0
release, so anyway we'd need to make a decision at least for 9.0.0.
We'd need to balance two (a bit conflicting) requirements.
- Give proper name to the vector codec. It should be sufficiently general and
also independent from any specific search algorithms/strategies. (in the spirit
of LUCENE-9322)
- The term "vector" is already overloaded. The codec and related classes
should be well-distinguished from existing classes/APIs.
I feel "NumericVectorsFormat" is the most balanced, well-grounded choice here
according to the discussion we have had so far. "numeric vector" is a very
general concept and will be open to various usage or algorithms that could be
proposed in the future. I'm thinking about preparing a patch or PR to rename
the codec (format) and the APIs that are tightly coupled with the codec; But I
am open to opinions/ideas from others, please feel free to leave comments if
you have any thoughts.

> Main points here are 1) use plural form for consistency, and 2) use more
> specific name for ann search (second point could be optional).
> A few alternatives were proposed:
> - VectorsFormat
> - VectorValuesFormat
> - NeighborsFormat
