Subject [jira] Commented: (CASSANDRA-1105) Create timers to reload cassandra-rack.properties and datacenters.properties
Date Tue, 25 May 2010 23:13:34 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-1105?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12871414#action_12871414

Jonathan Ellis commented on CASSANDRA-1105:
-------------------------------------------

A File object in Java is just a glorified String.  You don't want to be opening it here, just
checking the mtime.

> 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.
