             Summary: SolrCores.getCoreNames is quite inefficient and blocks other core operations
                 Key: SOLR-10742
                 URL: https://issues.apache.org/jira/browse/SOLR-10742
             Project: Solr
          Issue Type: Improvement
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Erick Erickson
            Assignee: Erick Erickson


SolrCores.getCoreNames iterates through all the cores to find all the aliases to this core. It does this in a synchronized block which blocks other core operations.

For installations with many cores this can be a performance issue. I'm not sure it makes sense to do it this way anyway, perhaps SolrCore should have a list of its current aliases and we can be more efficient about this? Or otherwise get this information in a less heavy-weight fashion?

I'm assigning this to myself to keep track of it, but anyone who wants to grab it please feel free.
