> Evaluate Variable value containing expression language
> I loaded custom properties into nifi.
> The registry variable called query has value "SELECT * FROM table WHERE id =
> ${id_no}" where the id_no is coming from the flowfile attributes. There was
> no functionality in nifi to evaluate the expression language inside the value.
> So, need to add functionality such that we can evaluate EL inside the
> variables.
> example: ${query:stringEl}
> where function `stringEl` will evaluate the EL value inside the query variable
