Sylvain Lebresne commented on CASSANDRA-1717: --------------------------------------------- As previously said, I both disagree on using 8 bytes when we need 4 and that using 4 is a matter for another ticket, but since this is probably me being too anal as usual, +1 on the rest of the patch, modulo a small optional nitpick: the toLong() function is a bit hard to read imho. It's hard to see where the parenthesis are, and if it does the right thing. It seems ok though, I just think a simple for loop on the bytes would be more readable. We also historically keep ByteBufferUtil for ByteBuffer manipulations and use FBUtilities for byte[] manipulation. > Cassandra cannot detect corrupt-but-readable column data > -------------------------------------------------------- > > Key: CASSANDRA-1717 > URL: https://issues.apache.org/jira/browse/CASSANDRA-1717 > Project: Cassandra > Issue Type: New Feature > Components: Core > Reporter: Jonathan Ellis > Assignee: Pavel Yaskevich > Fix For: 1.0 > > Attachments: CASSANDRA-1717-v2.patch, CASSANDRA-1717.patch, > checksums.txt > > > 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. -- This message is automatically generated by JIRA.
