In the Solr Wiki, Shawn Heisey writes the following: "Regardless of the number of nodes or available resources, SolrCloud begins to have stability problems when the number of collections reaches the low hundreds. With thousands of collections, any little problem or change to the cluster can cause a stability death spiral that may not recover for tens of minutes. Try to keep the number of collections as low as possible. These problems are due to how SolrCloud updates cluster state in zookeeper in response to cluster changes. Work is underway to try and improve this situation." https://wiki.apache.org/solr/SolrPerformanceProblems? action=diff&rev1=45&rev2=46
I'd like to know if this would apply to a standalone Solr system (embedded Zk) with one collection and the low hundreds of shards (e.g. 1 node, 1 collection and 200 shards). If there's any JIRA tickets we should track regarding the work that's underway to resolve this situation please provide them. Thanks! We are currently using 5.3.1
