By "instance" here I'm assuming you mean a JVM, i.e. running multiple
JVMs on a single physical node (host).

Unless you use recent Solt 7.x features where replicas can have different
properties[1], each replica is functionally the same at Solr level.
Zookeeper will elect a leader among them ( so temporary a replica will have
more responsibilities ) but (R1-R2-R3) does not really exist at Solr level.

Hi Shawn,
OK, got that.
Would shuffling or shifting the replicas bring any benfit or is it just wasted
time?

Beyond failure/maintenance concerns, the first setup is not necessarily a

could be much more prone to hot-spots in the cluster, especially if routing
or manual sharding is involved.
If for some reason, there are documents on
