Tomás Fernández Löbbe commented on SOLR-8344:
---------------------------------------------
bq. Because we already have to pay for seek cost for reading field1 therefore
reading other fields from stored will be faster than reading from DV
That would be my guess. But then, wouldn't we prefer to use stored fields for
all fields (if possible) if at least one of the fields needs to come from
stored fields? In the patch, it looks like, if rows >= 100, then we try to get
everything from DVs when possible, right?
> Decide default when requested fields are both column and row stored.

> 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?
