> In response to the discussion in https://github.com/apache/arrow/pull/8949/files#r588046787
> There are some performance penalties in the implementation of the compression codecs (e.g. data copying between heap/off-heap data). We need to revise the code to improve the performance. 
> We should also provide some benchmarks to validate that the performance actually improves.
