I feel I am confused because in the current migration process, there is already a `syncWAL` phase. How would `continuously synchronizing incremental data` be different? <img width="1126" height="849" alt="Image" src="https://github.com/user-attachments/assets/349dfb67-5d8c-49be-8d70-85d1f54d5669"; /> As described in the sequence diagram, the original migrate command automatically executes to the KSuccess status. By adding the DTSMODE and DTSCOMPLETE subcommands, the migration process is split into two phases: The first phase remains in the KWAL state, enabling continuous writes on the source node and simultaneous synchronization to the target node. The second phase reaches the KSuccess status, completing data synchronization. -- This is an automated message from the Apache Git Service.
