[I] [Java] Investigate potential performance improvement of compression codec [arrow-java]
asfimport opened a new issue, #388:
URL: https://github.com/apache/arrow-java/issues/388
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.
