Trino Parquet Column Encryption

[shangxinli]

Parquet modular encryption provides a column encryption feature. It would be great to have that in Presto. Due to the slowness of the PresteoDB, I would like to start the feature in TrinoDB. The original issue in PrestoDB can be found here.

It is a large feature and it can be divided into three parts: 1) Common code path 2) Decryption 3) Encryption. The command code path change and decryption change draft can be found here.

Hi, @shangxinli . I noticed that the previous PR has been closed, is there any progress on Parquet column encryption?

We at Apple have been running PME for a while now and would like to contribute the decryption support in Trino for it. We will be raising the draft PR soon for this. cc @vgankidi

@amoghmargoor Do you folks have any timeline to deliver the PME support for Trino? Thanks!

It seems this is no longer being actively worked on.

Feel free to re-open if needed.

I thin we should reopen it. cc @amoghmargoor

I have just opened a new PR for this rebased, PR is WIP as we are trying to add test cases for the encryption. #23583. This will have many newer files compared to existing PRs due to parquet-hadoop module being decoupled.
