Hi, I am just curious to know when Cassandra doc says the atomicity and isolation is guaranteed for a row. Does it mean, two requests updating a row- "R1" at different replica will be candidate for atomicity and isolation?
For instance , I have a setup where RF is 2 I have a client application where two requests of updating a particular row #R1 goes to two coordinator nodes at same time. Row "R1" has presence in nodes - N1, N2 (since RF is 2) Does Cassandra ensure atomicity & isolation across replicas/partition for a particular row? If so , then how does it get handled does Cassandra follows 2 Phase commit txn for a row or Cassandra uses distributed lock for a row? Thanks, Rajesh
