Problem Summary: Doris's table locks are fair read-write locks. If two threads acquire read locks on tables in different orders and simultaneously a third thread attempts to acquire a write lock on one of these tables, a deadlock can form between the two threads trying to acquire read locks. This PR changes the lock acquisition order for queries to follow the order of table IDs, ensuring that the lock acquisition order for tables is consistent among different threads. Execute table locking operations in ascending order of table IDs -- This is an automated message from the Apache Git Service.
