Brandon Williams commented on CASSANDRA-9909:
---------------------------------------------
bq. All this being said, DD.getSeeds() is called incredibly infrequently; in
fact, almost never.
I agree, only maybe once in OTC, when bootstrapping, or on removal of a seed
node.
> 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)
