[jira] [Commented] (CASSANDRA-12832) SASI index corruption on too
many overflow items
[ https://issues.apache.org/jira/browse/CASSANDRA-12832?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15648569#comment-15648569 ]
Pavel Yaskevich commented on CASSANDRA-12832:
---------------------------------------------
[~ifesdjeen] I don't think it's a good idea to log instead of throwing an exception in there, because throwing exception gives a clear indication that file is unusable where logging it would still make it look "ok" and loadable altough data is going to be missing...
