Xinli Shang created PARQUET-1792: ------------------------------------ Summary: Add 'mask' command to parquet-tools/parquet-cli Key: PARQUET-1792 URL: https://issues.apache.org/jira/browse/PARQUET-1792 Project: Parquet Issue Type: Improvement Components: parquet-mr Affects Versions: 1.12.0 Reporter: Xinli Shang Assignee: Xinli Shang Fix For: 1.12.0
Some personal data columns need to be masked instead of being pruned(Parquet-1791). We need a tool to replace the raw data columns with masked value. The masked value could be hash, null, redact etc. For the unchanged columns, they should be moved as a whole like 'merge', 'prune' command in Parquet-tools. Implementing this feature in file format is 10X faster than doing it by rewriting the table data in the query engine. -- This message was sent by Atlassian Jira (v8.3.4#803005)
