---------------------------------------

             Summary: Configuration is loaded too often during runtime
                 Key: CASSANDRA-9909
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-9909
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Robert Stupp
            Priority: Minor


Each call to {{SimpleSeedProvider.getSeeds()}} via {{DatabaseDescriptor.getSeeds()}} loads the configuration file from disk.

This is unnecessary in the vast majority of calls from {{Gossiper}} and {{StorageService}}.

Proposal:
* Instantiate {{ConfigurationLoader}} once during init of DD (not every time in {{loadConfig()}}}
* Only load configuration once per time interval
* Only load configuration if config file has changed (file modification timestamp) - if applicable (URL resolves to a file)
