------------------------------------
bq. I think we should remove it
Ok I will.
bq. It is unfortunate that the common case is often held back by the full
flexibility/generality of the facet module
With LUCENE-4647, the common case suffers less from the full generality of the
facets module. I'll open an issue to take care of FacetFields reusability and
there I hope I'll be able to tackle successfully the reusability of BytesRefs
for one as well as many CLPs.
IMO though, having a single entry point for users to index facets, be it 1
facet per document, or 2500 (a real case!), is important. We need to make sure
though that the 1 facet case is added the least overhead (e.g. using
Collections.singletonMap, or the trick I've done in
CountingListBuilder.OrdinalsEncoder (with/out partitions)).
> Explore IntEncoder/Decoder bulk API

> Project: Lucene - Core

> Today, IntEncoder/Decoder offer a streaming API, where you can encode(int)
> and decode(int). Originally, we believed that this layer can be useful for
> other scenarios, but in practice it's used only for writing/reading the
> category ordinals from payload/DV.
> Therefore, Mike and I would like to explore a bulk API, something like
> encode(IntsRef, BytesRef) and decode(BytesRef, IntsRef). Perhaps the Encoder
> can still be streaming (as we don't know in advance how many ints will be
> written), dunno. Will figure this out as we go.
> One thing to check is whether the bulk API can work w/ e.g. facet
> associations, which can write arbitrary byte[], and so may decoding to an
> IntsRef won't make sense. This too we'll figure out as we go. I don't rule
> out that associations will use a different bulk API.
> At the end of the day, the requirement is for someone to be able to configure
> how ordinals are written (i.e. different encoding schemes: VInt, PackedInts
> etc.) and later read, with as little overhead as possible.
