[jira] Commented: (CASSANDRA-1629) disallow memtable sizes <= 0

["Paul Bohm (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-1629?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12922466#action_12922466 ] 

Paul Bohm commented on CASSANDRA-1629:
--------------------------------------

Table.java:~275 in trunk 
            flushTask = StorageService.scheduledTasks.scheduleWithFixedDelay(runnable, minCheckMs, minCheckMs, TimeUnit.MILLISECONDS);

crashes cassandra when minCheckMs == 0, as can result from e.g. memtableFlushAfterMins == 0.

There's no easy way for users to recover from this. Probably both setting the memtable thresholds and above should have sanity checks.

> It's possible to create memtable size thresholds <= 0 currently.  If your thrift interface is old, this is easy to do accidentally, and we shouldn't allow this in general.
