------------------------------------
Summary: Make CLUSTERSTATUS command configurable
Key: SOLR-17381
URL: https://issues.apache.org/jira/browse/SOLR-17381
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Aparna Suresh
Fetching {{CLUSTERSTATUS}} remotely is resource-intensive and should be done
with caution. Currently, if no parameters are specified, the call returns all
information, including collections, shards, replicas, aliases, cluster
properties, roles, and more. This can have significant performance implications
for clients using a Solr cluster with thousands of collections.
Several performance [issues|https://issues.apache.org/jira/browse/SOLR-14985]
have been identified when switching {{CloudSolrClient}} to use HTTP-based CSP,
particularly in two instances where the entire cluster state is fetched
unnecessarily.
*Proposal:* Modify the requests to retrieve only the necessary information,
such as the cluster status for a specific collection, live nodes, or cluster
properties. Ensure these changes maintain backward compatibility. Additionally,
update the HTTP CSP to reflect these optimizations.
