Hi, all I submitted a pr to support three consistency levels: strong, mid and weak. (https://github.com/apache/incubator-iotdb/pull/1371) issue: https://issues.apache.org/jira/browse/IOTDB-722
Strong consistency means the server will first try to synchronize with the leader to get the newest meta data, if failed(timeout), directly report an error to the user; While mid consistency means the server will first try to synchronize with the leader, but if failed(timeout), it will give up and just use current data it has cached before; Weak consistency do not synchronize with the leader and simply use the local data. Please leave your opinions, thanks. ______________________________ Thanks, Houliang Qi
