> Each call to {{RangerRequestScriptEvaluator.evaluateScript()}} creates a
> binding. In case of row-filters having multiple expressions, as seen in
> following example, evaluateScript() is called as many times - resulting
> creation of multiple bundings for a given request. This can be avoided by
> moving creation of bindings to {{RangerRequestScriptEvaluator }}constructor.
