> Key: PARQUET-115
> URL: https://issues.apache.org/jira/browse/PARQUET-115
> Project: Parquet
> Issue Type: Improvement
> Components: parquet-mr
> Affects Versions: 1.6.0rc2
> Reporter: Yash Datta
> Priority: Minor
> Fix For: parquet-mr_1.6.0
>
>
> 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.
