[jira] [Created] (SPARK-31064) New Parquet Predicate Filter APIs with multi-part Identifier Support

DB Tsai created SPARK-31064:
-------------------------------

             Summary: New Parquet Predicate Filter APIs with multi-part Identifier Support
                 Key: SPARK-31064
                 URL: https://issues.apache.org/jira/browse/SPARK-31064
             Project: Spark
          Issue Type: New Feature
          Components: SQL
    Affects Versions: 2.4.5
            Reporter: DB Tsai


Parquet's *org.apache.parquet.filter2.predicate.FilterApi* uses *dots* as separators to split the column name into multi-parts of nested fields. The drawback is this causes issues when the field name contains *dot*.

The new APIs that will be added will take array of string directly for multi-parts of nested fields, so no confusion as using *dot* as a separator.

It's intended to move this code back to parquet community. See [PARQUET-1809]
