-------------------------------
Assignee: DB Tsai
> 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
> Assignee: DB Tsai
> Priority: Major
> Fix For: 3.0.0
>
>
> 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]
