Hi, We have an old production Cassandra 0.6.8 instance without replica, i.e., the replication factor is 1. Recently, we noticed that the snapshot data we took from this instance are inconsistent with the running instance data. For example, we took snapshot in early July 2011. From the running instance, we got a record that was created in March 2011, but on the snapshot copy, the record with the same key was different and was created in January 2011. Yesterday, we created another snapshot and reproduced the problem. I just like to know if this is a known issue for Cassandra 0.6.
We are going to migrate to Cassandra 0.8, but we need to make sure this will not be a problem in 0.8. Thanks in advance, John
