Subject [jira] [Commented] (CASSANDRA-1717) Cassandra cannot detect corrupt-but-readable column data
Date Fri, 05 Aug 2011 18:35:29 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-1717?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13080133#comment-13080133

Jonathan Ellis commented on CASSANDRA-1717:
-------------------------------------------

bq. can we consider making that compression only feature?

I'm fine with that.  We can always add the checksum-only uncompressed encoding later if someone
wants it badly enough. :)

> Most corruptions of on-disk data due to bitrot render the column (or row) unreadable,
so the data can be replaced by read repair or anti-entropy.  But if the corruption keeps column
data readable we do not detect it, and if it corrupts to a higher timestamp value can even
resist being overwritten by newer values.
