Assignee: Yuyuan KANG
> [Distributed] Enable schema auto-creation
> -----------------------------------------
>
> Key: IOTDB-709
> URL: https://issues.apache.org/jira/browse/IOTDB-709
> Project: Apache IoTDB
> Issue Type: Improvement
> Components: Core/Cluster
> Reporter: Tian Jiang
> Assignee: Yuyuan KANG
> Priority: Major
> Labels: cluster, schema
>
> Schema auto-creation is temporarily disabled in the distributed version because it modifies the metadata without notifying other nodes, causing potential inconsistency.
> To resolve this, one way is that the detection of missing schemas should be performed before the insertion being transformed into a raft log and append it to other nodes, and when missing schemas are found, the logs of creating missing schemas should be appended first to other nodes.
