Adrien Grand commented on LUCENE-7500:

I just looked again at how Fields are used, and I'd be tempted to just remove 
{{LeafReader.fields()}}. Consumers would have to call 
{{LeafReader.terms(String)}} instead. Fields would still be useful in 
{{CodecReader.getPostingsReader()}} (consistently with {{getNormsReader}}, 
{{getPointsReader}}, {{getDocValuesReader}} which all deal with all fields at 
once) and {{LeafReader.getTermVectors(int)}} for term vectors.

> Nuke Fields.java in lieu of LeafReader.getTerms(fieldName)

> {{Fields}} seems like a pointless intermediary between the {{LeafReader}} and 
> {{Terms}}. Why not have {{LeafReader.getTerms(fieldName)}} instead? One loses 
> the ability to get the count and iterate over indexed fields, but it's not 
> clear what real use-cases are for that and such rare needs could figure that 
> out with FieldInfos.
> [~mikemccand] pointed out that we'd probably need to re-introduce a 
> {{TermVectors}} class since TV's are row-oriented not column-oriented.  IMO 
> they should be column-oriented but that'd be a separate issue.
> _(p.s. I'm lacking time to do this w/i the next couple months so if someone 
> else wants to tackle it then great)_
