---------------------------------
Assignee: Houliang Qi
> [Distributed] Support mode consistencies
> ----------------------------------------
>
> Key: IOTDB-722
> URL: https://issues.apache.org/jira/browse/IOTDB-722
> Project: Apache IoTDB
> Issue Type: Improvement
> Reporter: Tian Jiang
> Assignee: Houliang Qi
> Priority: Major
> Labels: cluster, consistencyCheck
>
> We only support mid-consistency now, which is that we will first try to
> synchronize with the leader to reach strong consistency, but if there is a
> time-out, we will give up and just use current data which results in a weak
> consistency.
> So there are two other consistencies to support: Strong consistency, if there
> is a time-out, instead of using local data, directly report an error to the
> user. Weak consistency, do not synchronize with the leader and simply use the
> local data.
