Amareshwari Sriramadasu commented on LENS-122:
----------------------------------------------
bq. So with multiple expressions there will be one DenormalizationContext per
expression AST correct?
Denormalization resolver wont rewrite for expression. We need to add similar
rewriting in ExpressionResolver once the fact is picked.
> Add multiple expressions to expression column

> There can be multiple expressions for an expression column and then
> expression resolver should replace them lazily.

> # Allowing some fact tables to have expressions directly materialized
> # Having two different expressions in different facts for same expression
> column
