Xinli Shang created PARQUET-2062: ------------------------------------ Summary: 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
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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
