Cao Manh Dat commented on SOLR-8344:
------------------------------------
Thanks for your review, that's great.
bq. minor: It's debatable to me that RetrieveFieldsOptimizer is its own class.
It seems to me that a few static methods on DocsStreamer would be fine?
(package access for testing). No big deal though.
I think the purpose of the class is clear to me and this make the code look
better
bq. should we consider the presence of useDocValuesAsStored=false in one of the
fields that are both stored and docValues as a signal that we should not do
this optimization? I suppose so.
I maybe misunderstanding but {{useDocValuesAsStored=true}} only relate to
{{fl=*}} case and in that case, {{storedFields==null}} which is already skipped
in the patch.
> Decide default when requested fields are both column and row stored.

> this.
> If a given set of requested fields are all stored and have docValues (column
> stored), we can retrieve the values from either place. What should the
> default be?
