> 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.
