Xinli Shang created PARQUET-2116: ------------------------------------ Summary: Cell Level Encryption Key: PARQUET-2116 URL: https://issues.apache.org/jira/browse/PARQUET-2116 Project: Parquet Issue Type: Improvement Components: parquet-mr Reporter: Xinli Shang Assignee: Xinli Shang
Cell level encryption can do finer-grained encryption than modular encryption(Parquet-1178) or file encryption. The idea is only some fields inside the column are encrypted based on a filter expression. For example, a table with column a, b, c.x, c.y, d, we can encrypt column a, c.x where d == 5 and c.y > 0. -- This message was sent by Atlassian Jira (v8.20.1#820001)
