Does any one know which version of Cassandra supports conflict resolution based on internal Vector clock rather than by client supplied timestamps?

Vector clock conflict resolution(2 posts) (2 voices)
Some attempts have been made here in pre-release versions of 0.7.0, but nothing ever saw the light of day.
Current conflict resolution is solely based on a "highest-timestamp-wins" strategy depending on the consistency level specified for the operation.
Let us know if there are more questions here and we'll be happy to answer and/or direct you to specific documentation.
