Start by examining the fe.warn.log entry for BDBJEJournal.write():172 and the reported BDB journal batch size of 714271 during a streaming job. Reproduce the warning with Doris 4.1.3 using MySQL, then trace the journal-writing path to determine when this warning is emitted. Done means the warning is explained and an appropriate fix or documented resolution is verified.
