Nils Kilden-Pedersen updated CASSANDRA-8679:
--------------------------------------------
Description:
A failed LWT INSERT returns the row that prevented insertion, along with
{{[applied]}} boolean value. A successful LWT INSERT only returns {{[applied]}}.
It would be helpful to also return any other server generated values, e.g.
{{NOW()}} as {{[now]}} (or whatever).
There is currently no way to know what exactly was inserted without re-querying
the row, which is horrible for write-throughput.
