Hi, I'm testing Cassandra CAS operation.
Can a read operation read uncommitted data which is being updated by CAS in the following case? I use Cassandra 2.2.6. There are 3 nodes (A, B and C) in a cluster. Replication factor of keyspace is 3. CAS operation on node A starts to update row X (updating the value in row from 0 to 1). 1. prepare/promise phase succeeds on node A 2. node C is down 3. read/results phase in node A sends read requests to node B and C and waits for read responses from them. 4. (unrelated) read operation (CL: SERIAL) reads the same row X and gets the value "1" in the row!! 5. read/results phase fails by ReadTimeoutException caused by failure of node C Thanks, Yuji Ito
