> Currently for creating a user defined predicate using the new filter api,  no 
> value can be passed to create a dynamic filter at runtime. This reduces the 
> usefulness of the user defined predicate, and  meaningful predicates cannot 
> be created. We can add a generic Object value that is passed through the api, 
> which can internally be used in the keep function of the user defined 
> predicate for creating many different types of filters.
> For example, in spark sql, we can pass in a list of filter values for a where 
> IN clause query and filter the row values based on that list.
