Sylvain Lebresne commented on CASSANDRA-9909:
---------------------------------------------
bq. For proposal #3, you assume the seeds are being written out to a file,
which is not always the case
Pretty sure proposal #3 suggested to modify the reloading of the config within
{{SimpleSeedProvider}} (to, say, replace the call to {{loadConfig}} by a way to
reload the config only if it's not up-to-date and use that), so that wouldn't
affect other seed provider in the least and is imo a perfectly valid option. In
fact, I'd argue it's probably better than proposal #2.
> 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)
