> Affects Versions: 3.0.0, 3.0.1
> Reporter: Allison Wang
> Priority: Major

> Currently, the rule {{EliminateSorts}} removes a global sort node if its child plan already satisfies the required sort order without checking if the child plan's ordering is local or global. For example, in the following scenario, the first sort shouldn't be removed because it has a stronger guarantee than the second sort even if the sort orders are the same for both sorts.
> {code:java}
> Sort(orders, global = True, ...)
> Sort(orders, global = False, ...){code}
