Tomás Fernández Löbbe commented on SOLR-11982:
----------------------------------------------
Thanks [~emaijala], this looks really good. Again, I'm trying to unify the API
with the work done in SOLR-10880. SOLR-10880 attempts to filter the replicas
that can be used for resolving a query using {{shards.filter}}. It feels like
what you are doing here is sorting the replicas, to prefer some over others.
How do you feel about using the a parameter like {{shards.sort}}, and making
the value something like {{replicaType:PULL,replicaType:TLOG}}? {{local}} could
actually be just a keyword of this new parameter, and someone could do:
{{...&shards.sort=replicaType:PULL,local}} meaning "use replicas of type PULL
if available, otherwise prefer local cores, otherwise any replica}}. In the
future, the replica tags, as defined in SOLR-10880 could also be used for
sorting and not only for filtering (i.e.
{{...&shards.sort=local,replicaProp:rack1,replicaProp:dc1}}).
If so, we can deprecate {{preferLocalShards}}

> It would be nice to have the possibility to easily prefer certain replica
> types in a similar fashion to preferLocalShards. I'll be coming up with a
> patch that allows one to specify e.g. preferReplicaTypes=PULL,TLOG which
> would mean that NRT replicas wouldn't be hit with queries unless they're the
> only ones available.
