Scott Blum commented on SOLR-8745:
----------------------------------

Good call, I like forceUpdateCollection().  I don't see a strong need to rename 
the original method since we want to get rid of it.

> Deprecate ZkStateReader.updateClusterState(), remove uses

> Forcing a full ZK cluster state update creates a lot of unnecessary work and 
> load at scale.  We need to deprecate and remove existing callers.
> - The one at the start of ClusterStateUpdater thread is fine, it's a one-time 
> thing.
> - The one in OverseerCollectionMessageHandler is getting removed in SOLR-8722
> - The rest of them can be replaced with a version that only updates a single 
> collection; not everything!
> Patch will be forthcoming.
