Labels: LWT (was: )
> Implement "check and set"
> -------------------------
>
> Key: CASSANDRA-1984
> URL: https://issues.apache.org/jira/browse/CASSANDRA-1984
> Project: Cassandra
> Issue Type: New Feature
> Reporter: Max Sanders
> Priority: Major
> Labels: LWT
> Fix For: 0.7.1
>
>
> When fetching data from cassandra you should ask for a hash value for the
> stored value. Then when updating a value it should be possible to submit this
> hash value and only update the data when the hash key is still the same.
> This way you can be sure that the data was not changed on this node.
> It is the same as the memcached CAS Feature.
