[jira] [Created] (SPARK-31026) Enable Parquet predicate pushdown on columns with dots

DB Tsai created SPARK-31026:
-------------------------------

             Summary: Enable Parquet predicate pushdown on columns with dots
                 Key: SPARK-31026
                 URL: https://issues.apache.org/jira/browse/SPARK-31026
             Project: Spark
          Issue Type: New Feature
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: DB Tsai


Parquet predicate pushdown on columns with dots is disabled in -SPARK-20364- due to Parquet's APIs don't support it. A new set of APIs is purposed in PARQUET-1809 to generalize the support of nested cols which can address this issue. This implementation will be merged into Spark repo first until we get a new release from Parquet community.
