   There doesn't seem to have been any activity around this (or the attached JIRA) since September 2019. @ggershinsky Do you think it is worthwhile keeping this open?

> 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.
