I have also pushed an update to manage range transaction _dependencies_ in `CommandsForKey` as this is necessary for `mapReduce` on recovery. That is, when recovering a range transaction we need a way to know whether Key operations have witnessed it. It's not ideal, but I don't see a better all-round approach. This change is likely invisible to Cassandra until we implement full range reads, as we only utilise range exclusive sync points - which are invisible to everything except other exclusive sync points (which we never issue as Key operations in Cassandra). *BUT* we need it for correctness of the burn test that _does_ issue range transactions today, and it sets us up to handle it properly in Cassandra later. -- This is an automated message from the Apache Git Service.
