> We can build upon the API defined in {{fastparquet}} for defining RowGroup filters: https://github.com/dask/fastparquet/blob/master/fastparquet/api.py#L296-L300 and translate them into the C++ enums we will define in https://issues.apache.org/jira/browse/PARQUET-1158 . This should enable us to provide the user with a simple predicate pushdown API that we can extend in the background from RowGroup to Page level later on.
