[jira] Commented: (CASSANDRA-1872) Provide ability send notifications via JMX when an SSTable is written

["Peter Schuller (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-1872?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12984072#action_12984072 ] 

Peter Schuller commented on CASSANDRA-1872:
-------------------------------------------

Out of curiosity provably stemming from lack of JMX knowledge, how do you ensure that you don't miss events (under the assumption that one cannot guarantee to be connected to the JVM at all times); does one not need to have some kind of periodic fallback to iterating the file system anyway?

> One application of interest is the immediate backup of new SSTables. Relying on JMX's MBeanNotificationInfo would be a minimally intrusive to add "listeners" to CFS to facilitate this.
