Subject [jira] Commented: (CASSANDRA-1105) Create timers to reload and
Date Thu, 20 May 2010 04:35:54 GMT


Jon Hermes commented on CASSANDRA-1105:

Yeah, I should be able to do that by tomorrow.
The reloadConf calls can pass the name up to a bigger class, and it can pass
back the real filename after it's done the lookup and checked modification for the non-common
code to use.
Might be able to unduplicate the TimerTasks in the same way.

> 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.
