> Components: SQL
> Affects Versions: 2.2.1
> Reporter: Xiao Li
> Assignee: Xiao Li
>
> Currently, we do not guarantee an order evaluation of conjuncts in either
> Filter or Join operator. This is also true to the mainstream RDBMS vendors
> like DB2 and MS SQL Server. Thus, we should also push down the deterministic
> predicates that are after the first non-deterministic, if possible.
