Cassandra Targett commented on SOLR-15588:
------------------------------------------
A RandomPlacementFactory already exists for 9.0, as one of the 3 OOTB replica
placement options that will be available:
https://nightlies.apache.org/solr/draft-guides/solr-reference-guide-main/replica-placement-plugins.html.
I think it might be complex to add to 8.x - just based on what I know of what a
mess 8.x is in this regard - and both of the placement approaches available in
8.x are removed in 9.0 so it would also be throw-away work. But it sounds like
you have something working already? I could see an argument that it might be
helpful for people who need to stay on 8.x for a while, as a stopgap between
the current situation in 8.x and the replacement in 9.0. But IMO it should be
thought of and explicitly documented as a stopgap.

> Key: SOLR-15588
> URL: https://issues.apache.org/jira/browse/SOLR-15588
> Project: Solr
> Issue Type: New Feature
> Security Level: Public(Default Security Level. Issues are Public)
> Components: SolrCloud
> Affects Versions: main (9.0), 8x
> Reporter: Megan Carey
> Priority: Minor
>
> While this might be particularly interesting to users of 8x, it can also be
> made available in 9+: a replica placement strategy that randomly selects a
> node in the cluster (as long as no other replicas of that shard already live
> on that node).
> This has proven to be a valuable strategy for my use case, as it allows for
> really fast replica placement (-> fast collection creation, fast rebalancing,
> etc.), but it does not explicitly respect Autoscaling policies, so should be
> used wisely.
