ArnavBalyan opened a new pull request, #3281:
URL: https://github.com/apache/parquet-java/pull/3281
parquet-cli encryption-info <file>
- Since Parquet 1.12, encryption has become a first class citizen, with
support for footer and column level encryption.
- However, users have no clear way to check encryption metadata, mode, or
whether footer/file is encrypted.
- This PR adds a simple, dedicated CLI command: `parquet-cli
encryption-info <file>`
- The command reports the following:
- File-level encryption type: PLAINTEXT_FOOTER or ENCRYPTED_FOOTER.
- Summary of column encryption, per-column details and their encryption
status.
- No data decryption is attempted, if the footer encrypted, the CLI
clearly reports encrypted footer.
