DB Tsai updated SPARK-25559:
Description: Currently, in *ParquetFilters*, if one of the children
predicates is not supported by Parquet, the entire predicates will be thrown
away. In fact, if the unsupported predicate is in the top level *And* condition
or in the child before hitting *Not* or *Or* condition, it's safe to just
remove the unsupported one as unhandled filters. (was: Currently, in
*ParquetFilters*, if one of the children predicate is not supported by Parquet,
the entire predicates will be thrown away. In fact, if the unsupported
predicate is in the top level *And* condition or in the child before hitting
*Not* or *Or* condition, it's safe to just remove the unsupported one as
unhandled filters.)
