Uwe L. Korn commented on PARQUET-678:
-------------------------------------

Adding them to parquet-cpp and parquet-format is easy, the only thing that 
looks a bit harder from my side is to add to Hadoop as a codec so it can be 
used in parquet-mr. At least for Zstd, this seems to be done already:

> I understand that the list of accepted compression codecs is explicity 
> limited to uncompressed, snappy, gzip, and lzo. (See 
> parquet.hadoop.metadata.CompressionCodecName.java) Is there a reason for 
> this? Or is there an easy workaround? On the surface it seems like an 
> unnecessary restriction.
> I ask because I have written a custom codec to implement encryption and I'm 
> unable to use it with Parquet, which is a real shame because it is the main 
> storage format I was hoping to use.
> Other thoughts on how to implement encryption in Parquet with this limitation?
