EVALUATED
EVALUATE attempt to evaluate the RowExpression into a constant, even though it can be non-deterministic.
|

OPTIMIZED removes all redundancy in a RowExpression but can end up with non-serializable objects (e.g., Regex).
|
SERIALIZABLE
SERIALIZABLE guarantees the optimized RowExpression can be serialized and deserialized.
