> Encryption key material keeps the information required to recover the keys by
> Parquet readers. Currently, only "internal storage mode" is supported, where
> the key material is stored inside Parquet file footers, and therefore can't
> be rotated (re-wrapped with refreshed master keys) in immutable files. The
> new mechanism in this Jira adds the advanced "external storage mode" for the
> key material, where the key material is stored in separate small files, that
> enable the key rotation. This mechanism will also implement the key rotation
> functionality.
