Here we are using QUORAM to validate the expected columns. This will require nodes from more than one DC. We should use LOCAL_QUORAM here when CAS is done at LOCAL_SERIAL. Also if we have 2 DCs with DC1:3,DC2:3, a single DC down will cause CAS to not work even for LOCAL_SERIAL. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
