Sylvain Lebresne updated CASSANDRA-6623:
----------------------------------------
Attachment: 6623.txt
Attaching patch that fetch the full CQL row for CAS as we do for normal
selects. The patch did abstract a bit the conditions in SP.cas() so that we can
deal with the details of thrift and CQL separatly, which I think is a lot
cleaner anyway and is actually needed to lift a few of the current limitation
of the current patch on CASSANDRA-6561.
I'll note that the patch preserves the current behavior that a 'UPDATE IF'
implicitely check for the row existence, even if the conditions are all testing
for {{null}}. As said above, I don't know if that is the actual semantic we
want to preserve or if we want to change it.
> Null in a cell caused by expired TTL does not work with IF clause (in CQL3)

> IF onecell=null clause does not work if the onecell has got its null value
> from an expired TTL. If onecell is updated with null value (UPDATE) then IF
> onecell=null works fine.
> This bug is not present when you create a table with COMPACT STORAGE
> directive.
