[jira] [Created] (ARROW-6282) Support lossy compression

Dominik Moritz created ARROW-6282:
-------------------------------------

             Summary: Support lossy compression
                 Key: ARROW-6282
                 URL: https://issues.apache.org/jira/browse/ARROW-6282
             Project: Apache Arrow
          Issue Type: New Feature
            Reporter: Dominik Moritz


Arrow dataframes with large columns of integers or floats can be compressed using gzip or brotli. However, in some cases it will be okay to compress the data lossy to achieve even higher compression ratios. The main use case for this is visualization where small inaccuracies matter less.
