The "ReadRepair" page has been changed by JonathanEllis: http://wiki.apache.org/cassandra/ReadRepair?action=diff&rev1=5&rev2=6 - Read repair means that when a query is made against a given key, we perform a [[DigestQueries|digest query]] against all the replicas of the key and push the most recent version to any out-of-date replicas. If a low !ConsistencyLevel was specified, this is done in the background after returning the data from the closest replica to the client; otherwise, it is done before returning the data. + Read repair means that when a query is made against a given key, we perform a [[DigestQueries|digest query]] against all the replicas of the key and push the most recent version to any out-of-date replicas. If a lower !ConsistencyLevel than ALL was specified, this is done in the background after returning the data from the closest replica to the client; otherwise, it is done before returning the data. This means that in almost all cases, at most the first instance of a query will return old data.
