Shai Erera updated LUCENE-5618:
-------------------------------
Attachment: LUCENE-5618.patch
I modified SegDocValues API to take FieldInfos, and SegReader.initDocValues now
distinguishes between no-updates, with updates and back-compat logic. I wish we
didn't have the back-compat case, but that's what we have.
I'm still unsure about the getNumeric inefficiencies that you mentioned, so if
you can clarify I will try to address them here too. If it's a general SR
refactoring and simplification, I agree that we should pursue that in a
separate issue.

> Spinoff from LUCENE-5616.
> See the example there, docvalues readers get a fieldinfos, but it doesn't
> contain the correct ones, so they have invalid field numbers at read time.
> This should really be fixed. Maybe a simple solution is to not write
> "batches" of fields in updates but just have only one field per gen?
> This removes many-many relationships and would make things easy to understand.
