Ishan Chattopadhyaya commented on SOLR-8745:
--------------------------------------------
Instead of {{zkStateReader.forceUpdateCollection(collection)}}, can we overload
the updateClusterState method itself with the collection name as a parameter,
e.g. {{zkStateReader.updateClusterState(collection)}}? My thought is that
forceUpdateCollection gives a sense of a forceful update happening to a
collection, which is not the case here.
> Deprecate ZkStateReader.updateClusterState(), remove uses

> Key: SOLR-8745
> URL: https://issues.apache.org/jira/browse/SOLR-8745
> Project: Solr
> Issue Type: Improvement
> Components: SolrCloud
> Affects Versions: 5.4.1
> Reporter: Scott Blum

> Attachments: SOLR-8745.patch

>
> 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.
