[jira] [Created] (PARQUET-1659) Add AES-CTR to Parquet Encryption

Xinli Shang created PARQUET-1659:
------------------------------------

             Summary: Add AES-CTR to Parquet Encryption 
                 Key: PARQUET-1659
                 URL: https://issues.apache.org/jira/browse/PARQUET-1659
             Project: Parquet
          Issue Type: Improvement
          Components: parquet-cpp, parquet-format, parquet-mr
    Affects Versions: format-2.6.0
            Reporter: Xinli Shang


AES-GCM-CTR perform GCM encryption on metadata and CTR encryption on data.

AES-CTR would perform CTR encryption on both. 

During Perf testing, we found AES-CTR can improve read/write performance by ~10% comparing with AES-GCM-CTR.

 

I checked with Gidon and the initial assumption was that AES-GCM-CTR would have similar performance as AES-CTR. But with recent performance benchmarking, we found it is worthy to introduce AES-CTR. Since many companies strive for parquet performance improvement.
