> Add Codec.merge()
> -----------------
>                 Key: LUCENE-4057
>                 URL:
>             Project: Lucene - Java
>          Issue Type: Improvement
>    Affects Versions: 4.0
>            Reporter: Robert Muir
>             Fix For: 4.1
> Currently individual codec components can override/optimize merging, e.g. the stored
fields impl
> uses bulk copying when possible, and so on.
> SegmentMerger contains the logic for merging the different codec components, for example
it does
> mergeFieldInfos(), then mergeFields(), mergeTerms(), and so on. Each of these methods
> with the codec apis to finish the merge.
> I think it would be cleaner if SegmentMerger called a new method, Codec.merge(), which
> this logic instead. This way someone could customize this process. I think we could probably
> push some of the impl-dependent stuff (like matchingSegmentReaders) into the impl and
out of SegmentMerger.
> Setting this for 4.1, I think it would be a nice cleanup but I don't plan on working
on this immediately, 
> and I think we can do this in a backwards compatible way in a minor release.
