+In this query，there is a predicate `s.a is null` on the inner table `s`.
 
 From the `explain` results，we can see that the predicate is not pushed below join operator. This is because the outer join fills the inner table with `NULL` values when the `on` condition isn't satisfied, and the predicate `s.a is null` is used to filter the results after the join. If it is pushed down to the inner table below join, the execution plan is not equivalent to the original one.

 3. Check `drainer.log`. Search for the failed DDL operation and find the `commit-ts` of this operation. For example:
