Bloomfilter and dictionary comparison benchmarks:

   - PARQUET-41
   - Feedback to find the number of distinct values for which bloom filter
   outperforms filter based search
   - Action: JunJie to share code and update benchmark


   - Progress on multi-key design: need review
   - Need review on PR as well
   - Discussion on how to pass parameters down to Parquet to specify what
   to encrypt
   - Action: Gidon to share PR again and others to review.
