2011-02-22 Thread Jeremy.Truelove
More a less yes you must handle the synchronization, this only really becomes an issue when multiple hosts hit Cassandra and want to hit the same row/column at the same time, which is certainly possible but may not be common depending on your use case. this has a bit of info on the column leve
