Gidon Gershinsky commented on PARQUET-1178:
-------------------------------------------
[~Vatkov], a number of pull requests are under construction.
Hopefully they will be sent to the repository by the next week. No guarantees
they'll be merged by that time, but still you'll be able to assemble the
outstanding pr's, and build/run the encryption code.
> Parquet modular encryption
> --------------------------
>
> Key: PARQUET-1178
> URL: https://issues.apache.org/jira/browse/PARQUET-1178
> Project: Parquet
> Issue Type: New Feature
> Reporter: Gidon Gershinsky
> Assignee: Gidon Gershinsky
> Priority: Major
>
> A mechanism for modular encryption and decryption of Parquet files. Allows to
> keep data fully encrypted in the storage - while enabling efficient analytics
> on the data, via reader-side extraction / authentication / decryption of data
> subsets required by columnar projection and predicate push-down.
> Enables fine-grained access control to column data by encrypting different
> columns with different keys.
> Supports a number of encryption algorithms, to account for different security
> and performance requirements.
