--------------------------------
Summary: Add new APIs for nested predicate pushdown
Key: PARQUET-1809
URL: https://issues.apache.org/jira/browse/PARQUET-1809
Project: Parquet
Issue Type: New Feature
Components: parquet-mr
Reporter: DB Tsai
Currently, Parquet's *org.apache.parquet.filter2.predicate.FilterApi* is using
*dot* to split the column name into multi-parts of nested fields. The drawback
is that 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.
See https://github.com/apache/spark/pull/27728 and [SPARK-17636] for details.
