Jonathan Ellis commented on CASSANDRA-1105:
-------------------------------------------
> Would it be better to reload based purely on modified time instead of a
> minute timer?
No. We want to avoid doing the reload check during any performance-critical
code, and all the methods here that get called often enough to be useful for a
check, are performance-critical.
> Do we need to change the interface or just leave the option to manual-reload?
Delete PFSMBean and the methods it defines.
> Create timers to reload cassandra-rack.properties and datacenters.properties

>
> PropertyFileSnitch allows reloading changes from its config file manually.
> DatacenterShardStrategy doesn't allow reloading at all [after I ripped out
> the reload-for-each-getNaturalEndpoints call code, in CASSANDRA-1103].
> Let's check each of these for changes (modification time on the fs is
> sufficient) every minute and reload automatically if changes are seen. The
> manual-reload code from PFS can then be dropped.
