hi Parquet-dev, Wanted to reach out to see if anyone had thoughts on jira: https://issues.apache.org/jira/browse/PARQUET-682. Opened it to brainstorm around ideas on how we could configure which values writers were to be used for writing out data. We had some discussions around this in a PR I'd raised (https://github.com/apache/parquet-mr/pull/342), but that ended up just focussing on refactoring some of the code in parquet-column to enable these sort of use cases (and not tackling it).
The jira I linked has some potential approaches we can use for this. Would be great to get people's thoughts / use cases. Thanks, -- - Piyush
