Michael Sokolov commented on LUCENE-9855:
-----------------------------------------
# I agree this is a blocker - we don't want to be planning to rename this after
9.0
# Just to be completely explicit about what we are naming here, I'll repeat
the list from above; we are talking (I think) about renaming
o.a.l.codecs: VectorFormat, VectorReader, VectorWriter
o.a.l.index: VectorValues, VectorValuesWriter, RandomAccessVectorValues,
RandomAccessVectorValuesProducer
I think the proposal is to replace {{Vector}} in these names with {{NNVectors}}
or {{KNNVectors}}. I'd be fine with either, but have a slight preference for
consistent camel casing: {{NnVectors}} or {{KnnVectors}}. We can work out
issues around plurals and other details (KnnVectorsValues? KnnVectors? what
about the two writers?) once we agree on a specific "root name". I guess
{{KnnVectors }}would be my preferred choice{{.}}I don't see the K as
restrictive (we're always going to return some number - it doesn't imply
approximation or any algorithm), and it just seems more mellifluous to me :)

> Project: Lucene - Core

> There is some discussion about the codec name for ann search.
> https://lists.apache.org/thread.html/r3a6fa29810a1e85779de72562169e72d927d5a5dd2f9ea97705b8b2e%40%3Cdev.lucene.apache.org%3E
> 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
> - DenseVectorsFormat
