>             Project: Ignite
>          Issue Type: Improvement
>          Components: sql
>    Affects Versions: 3.0.0-beta2

>            Priority: Major
>
> Let's implement a utility for determining whether an expression tree 
> (RexNodes) is deterministic or not. 
> Expression is deterministic if it is constant expression, dynamic parameter, 
> or a function like CURRENT_TIMESTAMP is evaluated once per session, or 
> deterministic function.
> Non deterministic functions in AI-3: GEN_RANDOM_UUID.
> Check to see if there are any other non-deterministic functions as well and 
> mark them accordingly.
