Micah Kornfield commented on ARROW-11901:
-----------------------------------------
Does the presets library add a lot of value? Could this be done in a new
package within Arrow. I'm a little hesitant to take a new dependency (or would
at least want to do more research in terms of viability of the project/how
widely used the packages in the repo are used).
> [Java] Investigate potential performance improvement of compression codec

> 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.
