-------------------------------
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]
