Subject [jira] [Commented] (CASSANDRA-6413) Saved KeyCache prints success to log; but no file present
Date Mon, 02 Dec 2013 16:33:39 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-6413?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13836663#comment-13836663
] 

Chris Burroughs commented on CASSANDRA-6413:
--------------------------------------------

 * Yes, on every node in the cluster `saved_caches_directory` contains only a single file.
 * I don't see anything else relevant in the logs.  The log clip in the ticket is with AutoSavingCache
set to DEBUG logging.

> Cluster has a single keyspace with 3 CFs.  All used to have ROWS_ONLY, two were switched
to KEYS_ONLY about 2 days ago.  Row cache continues to save fine, but there is no saved key
cache file present on any node in the cluster.
