> Uniform encryption

> Key: PARQUET-2040
> URL: https://issues.apache.org/jira/browse/PARQUET-2040
> Project: Parquet
> Issue Type: Improvement
> Components: parquet-mr
> Affects Versions: 1.12.0
> Reporter: Gidon Gershinsky
> Assignee: Gidon Gershinsky
> Priority: Major
>
> PME low-level spec supports using the same encryption key for all columns,
> which is useful in a number of scenarios. However, this feature is not
> exposed yet in the high-level API, because its misuse can break the NIST
> limit on the number of AES GCM operations with one key. We will develop a
> limit-enforcing code and provide an API for uniform table encryption.
