> Data masking(null) for column encryption
> -----------------------------------------
>
> Key: PARQUET-2062
> URL: https://issues.apache.org/jira/browse/PARQUET-2062
> Project: Parquet
> Issue Type: New Feature
> Components: parquet-mr
> Reporter: Xinli Shang
> Assignee: Xinli Shang
> Priority: Major
>
> When user doesn't have permisson on a column that are encrypted by the column
> encryption feature (parquet-1178), returning a masked value could avoid an
> exception and let the call succeed.
> We would like to introduce the data masking with null values. The idea is
> when the user gets key access denied and the user can accept null(via a
> reading option flag), we would return null for the encrypted columns. This
> solution doesn't need to save extra columns for masked value and doesn't need
> to translate existing data.
