Hello Dremio Team,

1. Can we store dremio reflection as ORC format instead of Parquet, because compression rate of ORC wil be more than Parquet, even scan rate also.

2. Dremio reflection in Parquet format default using Snappy compression, can we change else like Gzip etc.

3. What was max compression rate(in %) achieved by dremio reflection.

Thanks,  
Ajay Babu Maguluri
