Description

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.
