   Thanks for the report.
   
   After checking the current Doris sink path, this looks closer to a real 
multi-table / save-mode gap than to a simple Doris 3.0 compatibility issue.
   
   The reason is that the job-side save-mode path is supposed to create missing 
sink tables before normal writing starts, and the Doris sink does wire 
`CREATE_SCHEMA_WHEN_NOT_EXIST` into that handler. But the actual failure you 
posted only appears later when the writer tries to stream-load data and Doris 
returns `table not found`. That suggests the target table creation path did not 
really cover this `MySQL-CDC + dynamic target table name` case.
   
   To narrow down where it breaks, we still need two precise pieces of 
information:
   1. did `ms_sync.z_auth_role` already exist before the job started, or was 
SeaTunnel expected to create it during startup?
   2. do the master / worker logs contain any `Creating table ...` save-mode 
log for `ms_sync.z_auth_role` before the first stream load starts?
   
   Once we have those two points, we can tell whether the miss is happening in 
the initial save-mode handling or later in the runtime multi-table 
materialization path.
   
   Also, for future follow-up in this repository, please update the thread in 
English if possible so more community members can help review it.
