Cao Manh Dat commented on SOLR-8344:
------------------------------------
[~tomasflobbe] I changed start param. Therefore, in the first pass, every shard
will send back 10010 ids back to the query master. Right now we will use stored
field to retrieve doc ids, with this patch, we will use doc values field to
retrieve doc ids ( which is significant faster ).
In case of less values to be retrieved ( case 2 ), the different is not much.
bq. What happens in your benchmark if at least one of the fields to return is a
text field (or has docValues=false)? Does getting the stored content of one of
the fields change your benchmark results?
Yeah, I'm about to testing that, we post result latter. But keep in mind that,
in case of multi-value field, we can't use docValues because values are stored
as sorted-set.
> 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
