Jason Brown updated CASSANDRA-13529:
------------------------------------
Resolution: Fixed
Fix Version/s: (was: 4.x)
4.0
Status: Resolved (was: Patch Available)
OK, finally got around to finish up the review here.
Everything was largely fine, but I've made some editorial choices:
- moved {{ArgSelect}} to {{SchemaStatement}}. it seems out of place in a
'utils' class.
- simplified implemention of {{dynamicConditionExists}} and moved it into
{{StressProfile}} and thus eliminated {{QueryUtils}}.
- eliminate the double checked locking in {{CASQuery.JavaDriverRun#bind()}} by
moving the {{client#bind()}} into the constructor of the {{JavaDriverRun}}.
- made some fields final and collections immutable in {{CASQuery}}
- i've made a few minor cleanups (nothing significant)
Committed as sha {{2aeed037e0f105e72366e15afa012257e910a25d}}. Thanks,

> It would be nice to have a light-weight transaction support in
> cassandra-stress.
> Although currently in cassandra-stress we can achieve light-weight
> transaction partially by using static conditions like "IF col1 != null" or
> "IF not EXIST".
> If would be ideal to have full fledged light-weight transaction support like
> "IF col1 = ? and col2 = ?". One way to implement is to read values from
> Cassandra and use that in the condition so it will execute all the paxos
> phases in Cassandra.
